Suppose the following data are selected randomly from a population of normally distributed values. 45 51 43 48 44 57 54 39 43 48 45 39 40 Construct a 95% confidence interval to estimate the population mean. What is the higher value of this interval? (Round the intermediate values to 2 decimal places, e.g. 25.31. Round your answers to 2 decimal places, e.g. 25.31.) Question 5 5 pts A community health association is interested in estimating the average number of maternity days women stay in the local hospital. A random sample is taken of 36 women who had babies in the hospital during the past year. The following numbers of maternity days each woman was in the hospital are rounded to the nearest day. 1 3 4 3 2 5 3 1 4 3 4 2 3 5 3 2 4 3 2 3 3 5 2 3 4 3 4 3 5 4 3 5 1 Use these data and a population standard deviation of 1.15 to construct a 98% confidence interval to estimate the average maternity stay in the hospital for all women who have babies in this hospital. What is the higher value of the interval? (Round the intermediate values to 3 decimal places, e.g. 25.316. Round your answers to 3 decimal places, e.g. 25.316.)
