-Without doing the calculations,state whether a larger or smaller sample would be required to guarantee that the probability that the sample mean differs from the population mean by more than 1.8 hours is less than 0.05,when compared to the sample needed to ensure that the probability that the sample mean differs from the population mean by more than 2.1 hours is less than 0.05.
