4. 11 Healthy adults' initial temperature (Temp 1) have been measured while sitting still, then their temperatures are measured again after laying down (Temp 2). \( \frac{\text { Subj }}{\text { Tem }} \) a) To test the claim that the mean temperature difference is 0 while sitting still vs. laying down, state the null and alternative hypotheses. b) At \( \alpha=0.01 \) significance level, find the critical value (round to 3 decimal places). c) Calculate the test statistics (round to 3 decimal places).
