- The Sample size of 100 students is taken from a large population. The mean height is 64 inches and S.D 4 inches. Can it be reasonably regarded population mean height is 66 inches. Would you conclude that there is no significant different between sample mean and hypothetical population mean. Table value @ 1% significant level is 2.58. Calculate Z test.
