Match the followings confidence intervals around the sample mean of xbar = 20 with the following conditions: N = 25, Sx = 15, 95% [ Choose ] confidence level N = 25, Sx = 15, 90% [Choose ] V confidence level Sx = 12, a = 0.05, df = 35 Choose V Sx = 12, a = 0.05, df = 8 Choose ]You hear that college campuses may differ from the general population in terms of political affiliation, and you want to use hypothesis testing to see if this is true and, if so, how big the difference is. You know that the average political affiliation in the nation is u = 4.00 on a scale of 1.00 to 7.00, so you gather data from 150 college students across the nation to see if there is a difference. You find that the average score is 3.46 with a standard deviation of 1.52. Conduct a two-tailed one-sample t-test to see if there is a difference at the a = 0.05 level. O Fail to reject (retain) the null hypothesis. There is no evidence that college campuses have lower political affiliation than the known average. O Reject the null hypothesis. There is no evidence that college campuses have lower political affiliation than the known average. O Reject the null hypothesis. There is evidence that college campuses have lower political affiliation than the known average. O Fail to reject (retain) the null hypothesis. There is evidence that college campuses have lower political affiliation than the known average
