A finite population is normally distributed with the mean = 50 and standard deviation=15. Assume a sample of size 49 is taken so that sample mean xbar can be employed to determine the population mean. The probability that the sample mean is less than or equal to 48 if the size of finite population is N=150
(a) 0.1236
(b) 0.2420
(c) 0.1544
