In a clinical trial of a cholesterol drug, 321 subjects were given a placebo, and 7% of them developed headaches. for such randomly selected groups of 321 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

The value of n is 321.

Step-by-step explanation:

Since we have given that

Sample size = 321

Percentage of them developed headaches = 7%

So, the value of p would be

Now, the value of q would be

And the mean for the number of subjects who develop headaches would be

and the standard deviation would be

Hence, the value of n is 321.
