Question
The mean and variance of a random sample of 64 observations were computed as 160 and 100 respectively. (i) Compute the 95% confidence limits for population mean. (ii) If the investigator wants to be 95% confident that the error in estimate of population mean should not exceed ± 1.4, how many additional observations are required?
