Question

In a clinical trial of a cholesterol drug, 456 subjects were given a placebo, and 22% of them developed headaches. For such randomly selected groups of 456 subjects given a placebo, identify the values of n, p, and q that would be used

for finding the mean and standard deviation for the number of subjects who develop headaches.
The value of n is 268
The value of p is 0.24
(type an integer or a decimal.)
The value of q is 0.76
(type an integer or a decimal)

Answer 1

In a clinical trial of a cholesterol drug, the values of n, p, and q would be used to find the mean and standard deviation for the number of subjects who develop headaches.

Step-by-step explanation:

In this case, the values of n, p, and q would be used to find the mean and standard deviation for the number of subjects who develop headaches.

The value of n refers to the total number of subjects, which in this case is 456.

The value of p represents the probability that a subject will develop headaches, which is given as 22% or 0.22.

The value of q is the complement of p, which is 1 - p, so q = 1 - 0.22 = 0.78.

Using these values, we can calculate the mean and standard deviation for the number of subjects who develop headaches.
