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.)
