According to Facebook's self-reported statistics, the average Facebook user is connected to 80 community pages, groups, and events. For a statistics project, a student at Contra Costa College tests the hypothesis that CCC students will average less than 80 such connections. She posts a survey on her Facebook page. Her sample contains 45 responses. She chooses a 5% level of significance. From her data she calculates a t-test statistic of approximately -1.74 with a P- value of about 0.04. What can she conclude? A. O Nothing. The conditions for use of a t-test are not met. She cannot trust that the P-value is accurate for this reason. B. The data is not statistically significant. In other words, the data do not provide enough evidence to conclude that the
