Will eating oatmeal promote healthy levels of cholesterol? A consumer reports analyst took a sample of 31 people with high cholesterol and asked them to eat oatmeal once a day for 3 months. Measurements were taken of their cholesterol levels before and after the 3 months in mg/dl. The analyst is testing whether the cholesterol levels after the diet are greater than the cholesterol levels before the diet. The hypotheses for this test are as follows: Null Hypothesis: Up $ 0, Alternative Hypothesis: Up > 0. If the analyst calculated the mean difference in cholesterol levels (after - before) to be -1.84 mg/dL with a standard deviation of 14.08 md/dL, what is the test statistic and p-value for the paired hypothesis t-test? 1) Test Statistic: -0.728, P-Value: 1.528 2) Test Statistic: 0.728, P-Value: 0.236 ( 3) Test Statistic: 0.728, P-Value: 0.764 ( 4) Test Statistic: -0.728, P-Value: 0.764 ( 5) Test Statistic: -0.728, P-Value: 0.236
