It has been observed that social media has been very attractive to the millennials and has been used as a major platform where they can share their experiences, emotions, and others. A group of senior high school students is interested to know the length of time a senior high school student spends in a week browsing his or her social media account(s). The data which they gathered is recorded in the table below. Attention Time (in hours) in a Week Given to Social Media Accounts for a Random Sample of n = 25 20.5 3.4 20.7 12.1 2.9 21.5 5.4 32.0 32.6 35.6 12.9 33.1 14.0 15.4 29.4 4.1 36.4 0.8 8.3 13.4 15.2 32.5 10.1 5.7 15.4 Suppose that the length of attention time in a week given to social media accounts by the 25 senior high school students is normally distributed, find a 99% confidence interval for o. Interpret the result.
