Cholesterol Levels A medical researcher wishes to see if he can lower the cholesterol levels through diet in 6 people by showing a film about the effects of high cholesterol levels. The data are shown. At α=0.01, did the cholesterol level decrease on average? Use the P-value method and a graphing calculator. Patient:   1,      2,     3,     4,      5,     6 Before: 240, 211, 209, 216, 211, 219 After:    216, 205, 195, 194, 205, 213 (a) State the hypotheses and identify the claim with the correct hypothesis. H0: μ=D0  ▼not claim   H1: μ>D0  ▼claim This hypothesis test is a ▼one-tailed test. (b) Compute the P-value. Round the answer to at least four decimal places. P-value=___________________
