41. Independent random samples are selected from two populations. Below are the sorted data from the first population. 53.2 54.2 54.7 55.3 55.9 56.0 56.3 57.0 58.2 58.5 58.7 61.0 62.5 62.8 64.4 66.3 67.0 69.0 Hint: The mean and standard deviation of these numbers are 59.50 and 4.80. Below are the sorted data from the second pop- ulation. 49.2 53.8 56.9 57.8 58.1 58.4 62.0 65.4 69.4 Hint: The mean and standard deviation of these numbers are 59.00 and 6.00. (a) Calculate Gosset's 90% confidence inter- val for the mean of the first population. (b) Calculate a confidence interval for the me- dian of the second population. Select your confidence level and report it with your answer.
