PROBLEM 3

Suppose data about the average number of hours people spend on social media websites at work is randomly collected for 7 days:

5.2, 4.6, 2.9, 4.2, 2.7, 3.3, 3

1. If we assume this population is normally distributed, construct an 98% confidence interval for the population average amount of time people spend on social media websites at work.
2. Suppose I want to know more about how workers spend their time throughout the day. I want to find evidence to prove the claim that people spend at least 3 hours a day (during their workday) on social media. Test this claim (significance level =0.1).
