4. Suppose that the distribution of height of female students in University is normally distributed with mean =1.6 meters and o = 0.02 meters. A sample of 100 female students drawn randomly from all the female students in University had an average height of 1.61 meters. (1) In this case, what are the population and sample, respectively? (2) Give the point estimate of the population mean. (3) Establish a 95 percent confidence interval for the population mean height (= 1.6)
