The average annual cost of books for a random sample of 20 college students in both public and private schools was $1114. Assuming that the population standard deviation is $186 and the distribution is approximately normal, construct a 92% confidence interval for the mean annual cost of books for both public and private schools. (1041.2, 1186.8) (1045.6, 1182.4) (1032.5, 1195.5) (1037.1, 1190.9) (1026.9, 1201.1)
