Perform hypothesis testing on one variable’s data. (Choose either the intrinsic or extrinsic column.) Perform a ttest by formulating a null and an alternative statement, choosing an acceptable significance value, determining the appropriate critical value, selecting the test statistic and determining its value from the sample data, comparing the observed value to the critical value obtained and determining whether to reject or fail to reject the null hypothesis

Have you been given some data upon which to perform the hypothesis testing procedure? If so, we'll need to see it too in order to help.
