A publisher wants to estimate the mean length of time (in minutes) all adults spend reading newspapers. To determine this estimate, the publisher takes a random sample of 15 people and obtains the results below. From past studies, the publisher assumes σ is 2.3 minutes and that the population of times is normally distributed.Sample data: 11, 10, 7, 10, 12, 12, 6, 9, 12, 8, 7, 11, 11, 6, 6Construct the 90% and 99% confidence intervals for the population mean. Which interval is wider? If convenient, use technology to construct the confidence intervals.The 90% confidence interval is [ , ].

Estimate the true mean population distraction time with 90% confidence, and compare your answer to the results of the study. (1.654,1.946). Mean of the study is outside or "different" from the result of our study.
