Use the t distribution to construct the confidence interval estimate of the population mean. Round the confidence interval estimates to one decimal place unless indicated otherwise.

A sociologist develops a test to measure attitudes about public transportation, and a simple random sample of 27 subjects are given the test. Their mean score is 76.2 and their standard deviation is 21.6. Assume that the population of these scores is normally distributed. Construct the 95% confidence interval estimate of the population mean.
◦ 67.7 < μ < 84.7
◦ 69.2 < μ < 83.2
◦ 64.2 < μ < 88.2
◦ 74.6 < μ < 77.8
