Suppose that the average time spent per day with digital media several years ago was 3 hours and 44 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 95% condence interval for last year's mean time spent per day with digital media by adults of the region. (Note: )_(= 5.11 hr and s = 2.28 hr.)
