Given a normal population whose mean is 590 and whose standard deviation is 53, find each of the following (use Excel to obtain more accuracy):
A. The probability that a random sample of 5 has a mean between 602 and 614.
Probability =
B. The probability that a random sample of 13 has a mean between 602 and 614.
Probability =
C. The probability that a random sample of 21 has a mean between 602 and 614.
Probability =
