4. (10+5+5 points) In 2018, the SSBU faculty surveyed the school and determined that students on average spend 2.5 hours a night on schoolwork. We are interested in repeating a similar study in 2024, to determine if students still spend about that much time studying each night. (a) One instructor posts a link to a survey and asks for willing participants to report on the number of hours studied each night and after several offerings of courses feels they've accrued a large enough sample to start computing, and obtain 3,8 2, N = 64. Perform an appropriate hypothesis test using these statistics to support a relevant conclusion. (b) Identify a possible source of sampling bias.
