Suppose that you collect a random sample of 250 salaries for the salespersons employed by a large PC manufacturer. Furthermore, assume that you find that two of these salaries are considerably higher than the others in the sample. Before analyzing this data set, should you delete the unusual observations
Answer:
It depends and analysis maybe with the values kept and with the values deleted depending on what we intend to find with the data.
Step-by-step explanation:
When conducting data analysis, a large chunk of time is usually spent trying to ensure that the data is prepared to be used for the require analysis. To ensure this, we tidy up the data by doing the following :
Changing the data format for variables whose units do not conform and so on.
The method of dealing with missing data is essential during data analysis. Missing data may be replaced with the mean value of the observation or completely removed. Based on the scenario, the sample size is 250 ; number of values with unusually high salary values are just 2, hence, removing this values shouldn't pose much of a threat to our data and shouldn't have much effect on the outcome. Hence, removing the Outliers.
Similarly, this unusually high values may signify certain purpose or give certain critical information about the salary and hence may not be deleted
Depending on what we hope to discover from the data, an analysis may be performed
What is a random sample?A simple random sample is a subset of persons picked at random, all with the same probability, from a larger set of individuals. It is a method of choosing a sample at random.
When performing data analysis, a significant amount of work is typically dedicated to making sure the data is ready to be used for the required analysis. We clean up the data in the following ways to make sure of this
changing the data format for variables with non-conforming unit measurements.
During data analysis, the way missing data are handled is crucial. Missing data can either be fully eliminated or replaced with the observation's mean value. According to the scenario, the sample size is 250 there are only 2 values with abnormally high salary values, therefore deleting these values shouldn't constitute significant harm to our data or have a significant impact on the results. thus eliminating the Outliers

To celebrate 24 years in business, a clothing store's marketing executive is ordering scratch-off discount coupons to give to customers. She would like 40% of customers in the population to receive the highest possible discount, with an SEP of 0.01 for this population. How many coupons should she order?
Answer:
She should order 2400 coupons.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
She would like 40% of customers in the population to receive the highest possible discount, with an SEP of 0.01 for this population.
This means that [tex]p = 0.4, s = 0.01[/tex]
How many coupons should she order?
We have to find n. So
[tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
[tex]0.01 = \sqrt{\frac{0.4*0.6}{n}}[/tex]
[tex]0.01\sqrt{n} = \sqrt{0.4*0.6}[/tex]
[tex]\sqrt{n} = \frac{\sqrt{0.4*0.6}}{0.01}[/tex]
[tex](\sqrt{n})^2 = (\frac{\sqrt{0.4*0.6}}{0.01})^2[/tex]
[tex]n = 2400[/tex]
She should order 2400 coupons.

I'LL GIVE BRAINLIST!!! 1. Find the missing parts of the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropriate.
C = 109.3°
a = 5.6 km
b = 10.7 km
Answer:
c=13.6km, B=47.9⁰, A=22.8⁰,
Using the cosine rule, the missing parts of the triangle are:
c = 13.6 km; B = 47.9°; C = 22.8°
What is the Cosine Rule?Cosine rule is given as, c² = a² + b² ﹣ 2ab(cosC)
Given the following:
C = 109.3°a = 5.6 kmb = 10.7 kmFind c using the cosine rule:
c² = 5.6² + 10.7² ﹣ 2(5.6)(10.7)(cos 109.3)
c² = 185.5
c = √185.5
c = 13.6 km.
Use the cosine rule to find A:
5.6² = 10.7² + 13.6² ﹣ 2(10.7)(13.6)(cosA)
31.36 = 299.45 ﹣ 291.04(cosA)
31.36 - 299.45 = ﹣ 291.04(cosA)
-268.09 = ﹣ 291.04(cosA)
0.9211 = (cosA)
C = cos^(-1)(0.9211)
C = 22.8°
Find B:
B = 180 - 22.8 - 109.3
B = 47.9°
Therefore, using the cosine rule, the missing parts of the triangle are:
c = 13.6 km; B = 47.9°; C = 22.8°

Factorizie completely 2ap+aq-bq-2bp
Answer:
2ap + aq - bq -2bp = (a - b)(2p + q)
Step-by-step explanation:
(2ap + aq) - (bq -2bp)
a(2p +q) -b(q + 2p) [ taking a common from the first, and b from the second]
(2p + q) [a - b] [takin (2p + q)]
(2p + q)(a - b)
The completely factored form of the expression 2ap + aq - bq - 2bp is
(a - b)(2p + q).
In order to completely factorize the given expression, we need to look for common factors and apply factorization techniques.
Given expression: 2ap + aq - bq - 2bp
Step 1: Look for common factors.
Notice that 'a' is common in the first two terms, and '-b' is common in the last two terms.
Step 2: Factor out the common terms.
We can factor 'a' from the first two terms: a(2p + q)
And factor '-b' from the last two terms: -b(q + 2p)
Step 3: Rearrange the expression.
Now we have: a(2p + q) - b(q + 2p)
Step 4: Factor by grouping.
We can see that (2p + q) is common in both terms, so we can factor it out: (2p + q)(a - b)
Step 5: Final result.
Thus, the completely factored form of the given expression is
(a - b)(2p + q).

Suppose x is a normally distributed random variable with a mean of 12 and a standard deviation of 3. The probability that x equals 19.62 is _____.
Answer:
The probability that x equals 19.62 is 0
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In the normal probability distribution, the probability of an exact value, that is, P(X = x) is 0. Thus, the probability that x equals 19.62 is 0

Lou says to his granddaughter Audrey, "Even if you tripled your age and added 9, you still wouldn't be as old as I am.” Lou is 60 years old. Write and solve an inequality to determine the possible ages Audrey could be.
Answer:
3x+9 < 60 where x = Audrey's age
Step-by-step explanation:
Lou says "even if you tripled you age", which means that if Audrey's age is represented by the variable x, then we would multiply it by 3 to get 3x. the next part says "and add 9". We already have the 3x, so we would just tack on a +9 to get 3x + 9. The last part says "you still wouldn't be as old as me." Given that 3x+9 represents Audrey's age, this equation would have to be less than Lou's age, which in this case is 60.

a. A number relatively close to 1.
b. A number relatively close to 10.
c. A number relatively close to 100.
d. A number relatively close to 500.
e. A number relatively close to 1000.
Answer:
c. A number relatively close to 100.
Step-by-step explanation:
Given
[tex]Range: 0 \to 1[/tex]
[tex]N =1000[/tex] --- i.e. the cells
Required
Number of cells that contains less than or equal 0.2
Less than or equal 0.2 means that the numbers are approximately 20% of the whole distribution
So, to calculate the number (n) of these cells, we do the following computation
[tex]n = 20\% * N[/tex]
[tex]n = 20\% * 1000[/tex]
[tex]n = 200[/tex]
200 is closer to 100 than 500. Hence, (c) is correct

<ACE = 130
180 - 50 = 130
Now that we have two sides and an included angle, we can use the Law of Cosines.
Law of Cosines: c^2 = a^2 + b^2 - 2ab(cos(C))
Let's plug in what we know and solve!
c^2 = 40^2 + 38^2 - 2(40)(38)(cos(130))
R = 70.69706
Hope this helps!! :)
Answer:
R =70.6970629
Step-by-step explanation:
We need to use the law of cosines since we have 2 sides and the included angle
The angle inside is 180 -50 = 130
c^2 = a^2 + b^2 − 2ab cos(C) where c is the side opposite the unknown angle
R^2 = 40^2 + 38^2 - 2*40 *38 cos (130)
R^2 = 1600 -1444-3040cos 130
R^2 = 3044-3040cos130
R^2 =4998.074333
Taking the square root of each side
sqrt(R^2) = sqrt( 4998.074333)
R =70.6970629

A bag contains exactly 50 coins. The coins are either worth 10 cents, 20 cents or 50 cents and there is Atleast one of each. The total value of the coins is $10. How many different ways can this occur?
Answer:
This can happen in two ways:
1) 42 20-cent coins, 6 10-cent coins and 2 50-cent coins.
2) 30 10-cent coins, 10 20-cent coins and 10 50-cent coins.
Step-by-step explanation:
Given that a bag contains exactly 50 coins, and the coins are either worth 10 cents, 20 cents or 50 cents and there is at least one of each, and the total value of the coins is $ 10, to determine how many different ways can this occur, the following calculation must be performed:
48 x 0.5 + 1 x 0.2 + 1 x 0.1 = 24.30
48 x 0.1 + 1 x 0.2 + 1 x 0.5 = 5.5
48 x 0.2 + 1 x 0.1 + 1 x 0.5 = 10.3
45 x 0.2 + 4 x 0.1 + 1 x 0.5 = 9.9
44 x 0.2 + 5 x 0.1 + 1 x 0.5 = 9.8
42 x 0.2 + 6 x 0.1 + 2 x 0.5 = 10
30 x 0.1 + 10 x 0.2 + 10 x 0.5 = 10
Therefore, this can happen in two ways:
1) 42 20-cent coins, 6 10-cent coins and 2 50-cent coins.
2) 30 10-cent coins, 10 20-cent coins and 10 50-cent coins.
