A clothing company sells slacks that are either blue or gray and pleated or non-pleated. Last month, the company sold 5 times as
qwelly [4]

Answer:

138 pairs

Step-by-step explanation:

The number of blue pleated slacks is 5 times the number of gray pleated slacks, so:

blue\ pleated = 5 * gray\ pleated (eq1)

The number of gray non-pleated is twice the number of blue non-pleated slacks, so:

blue\ nonpleated = 2 * gray\ nonpleated (eq2)

The total number of blue slacks is 333, and the total number of gray slacks is 225, so we have that:

blue\ pleated + blue\ nonpleated = 333 (eq3)

gray\ pleated + gray\ nonpleated = 225 (eq4)

If we add (eq1) and (eq2), we have:

blue\ pleated + blue\ nonpleated = 5*gray\ pleated + 2*gray\ nonpleated (eq5)

Using (eq3) and (eq4) in (eq5), we have:

333 = 2*225 + 3*gray\ pleated

gray\ pleated = 117/3 = 39

From (eq1), we have:

blue\ pleated = 5*39 = 195

From (eq3), we have:

blue\ nonpleated = 333 - 195 = 138

What is the name for the threshold​ p-value that determines when the null hypothesis is​ rejected?.
Anna [14]

Alpha level. the minimum P-value at which we reject the null hypothesis

<h3>What is Null hypothesis ?</h3>

That two options are identical is the null hypothesis. According to the null hypothesis, the observed difference is solely the result of chance. The probability that the null hypothesis is correct can be determined via statistical testing.

<h3>What is alpha level?</h3>

The "significance level," often known as the alpha level, must be established before performing any statistical test. The likelihood of rejecting the null hypothesis when it is true is what is meant by the term "alpha level" in statistics. The likelihood of making a poor decision is what this phrase means.
