Suppose that the average time spent per day with digital media several years ago was 3 hours and 25 minutes. For last year, a random sample of 20 adults in a certain region spent the numbers of hours per day with digital media given in the accompanying table. Preliminary data analyses indicate that the t-interval procedure can reasonably be applied. Find and interpret a 99% confidence interval for last year's mean time spent per day with digital media by adults of the region. (Note: -5.42 hr and s 2.26 hr.)
