Many students brag that they have more than 150 friends on a social media platform. For a class project, a group of students asked a random sample of 13 students at their college who used the social media platform about their number of friends and got the data available below. Is there strong evidence that the mean number of friends for the student population at the college who use the social media platform is larger than 150?
