d) Use Excel Data Analysis function, at 0.01 significance level, compare the two paired sample mean, submit a screenshot of the result output. (t Stat from the output should match your answer in part c).e) Based on your answer from c) or d), at a = 0.01 level, what is your conclusion?

4. 1 1 Healthy adults' initial temperature (Temp 1) have been measured while sitting still, then their temperatures are measured again after laying down (Temp 2).
