sociologist develops a test to measure attitudes towards public transportation, and n = 27 randomly selected subjects are given the test. Their mean score is x̄ = 76.2 and their standard deviation is σ = 21.4. Construct the 95% confidence interval for the mean score of all such subjects.   Use the given degree of confidence and sample data to construct a confidence interval for the population mean μ. Round your final answers to the nearest hundredth.   You will need to calculate the margin of error, followed by the lower and upper end of the confidence interval
