In a clinical trial of a cholesterol drug, 314314 subjects were given a placebo, and 1212 % of them developed headaches. For such randomly selected groups of 314314 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 values of n, p and q are 314, 0.12 and 0.88 respectively.

Explanation:

n is the number of subjects given a placebo. The value of n is 314.

p is the sample proportion of the subjects given a placebo that developed headaches. The value of is 12% = 0.12

q is the sample proportion of the subjects given a placebo that did not develop headaches. The value of q = 1 - p = 1 - 0.12 = 0.88
