For this study, we should use t-test for the difference between two dependent population mean: a. The null and alternative hypotheses would be: Ho: μd 0 H₁: 0 ud (please enter a decimal) (Please enter a decimal) b. The test statistic show your answer to 3 decimal places.) c. The p-value = (please (Please show your answer to 4 decimal places.
