We have 30 pairs of data with a mean of differences of 125 and standard deviation of 2000. Test the claim that the mean difference is positive at alpha = 0.01. What is the distribution of the test statistic? What is the DF of the distribution of the test statistic? What is the standard error? Does the confidence interval reject the claim? Test the claim that the mean difference is negative at alpha = 0.01
