A. For classes of 92 students, find the mean and standard deviation for the number born on the 4th of july. Ignore leap year.

B. For a class of 92 students, would two be an unusually high number who wereborn on the 4th of july?

A. the value of the mean is u=? (round to 6 decimal places)

the value of standard deviation is o= ? (round to 6 decimal Places)

B. Would 2 be an unusally high numbers of individuals who were born on the 4th of july?

Binomial with n = 92 and P(born on 7/4) = 1/365
------
mean = np = 92 (1/365) = 0.2520

std = sqrt(npq) = sqrt(0.2520*(364/365)) = 0.5013
