From the Your Turn on p. 454: Sprint would like to investigate if men and women differ in how many minutes they talk on their cell phones per month. Assume the population variances are not equal. The data is below. Give the lower limit for a 99% confidence interval for the difference (women minus men). You should get the pieces needed for this confidence interval from the Data Analysis Toolpak in Excel. Round your answer to two decimal places.
