Question

According to Facebook's self-reported statistics, the average Facebook user spends 55 minutes a day on the site. For a statistics project a student at Contra Costa College tests the hypothesis that CCC students spend more than 55 minutes a day on site. She randomly selects 2 classes from the class schedule and distributes surveys in those classes. She collects data from 21 students. Here is her data. What do you recommend? A) She should run the hypothesis test for a population mean because the data meets the conditions for use of a T-model. B) She should gather more data to get her sample size up to more than 30. C) The data is skewed with outliers. This is unlikely to change with the collection of more data. She will not be able to proceed with a hypothesis test. She should find another research question. D) She should remove the two outliers from the data and proceed with the hypothesis test for a mean.
