In a clinical trial of a cholesterol drug, 374 subjects were given a placebo, and 21% of them developed headaches. for such randomly selected groups of 374 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 (do not round.) the value of p is (type an integer or a decimal. do not round.) the value of q is (type an integer or a decimal. do not round.)

The value of n is  374. The value of p is 0.21. The value of q is 0.79.

Step-by-step explanation:

Given : In a clinical trial of a cholesterol drug, 374 subjects were given a placebo, and 21% of them developed headaches.

∴ Sample size :

The probability that cholesterol drug developed headaches :

Then , the probability that cholesterol drug did not develop headaches :

Hence, The value of n is  374.

The value of p is 0.21.

The value of q is 0.79.
