Assume the following for a paired-samples t test: N = 12, M_difference = 635.65, s = 608.50.What is the t statistic?

Question

To calculate the t statistic, we need to use the formula t = (M - µ) / (s / √N), where M is the mean difference, µ is the population mean difference (which we assume to be 0), s is the standard deviation of the differences, and N is the sample size. Plugging in the values from the problem, we get t = (635.65 - 0) / (608.50 / √12) = 3.62. Therefore, the correct choice is C.
