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 o is 2.3 minutes and that the population of times is normally distributed. 11 10 10 12 12 6. 9. 12 8 11 11 6. Construct 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 ( (Round to one decimal place as needed.) Enter vour answer in the edit fields and then click Check Answer
