The Ankle Brachial Index (ABI) compares the blood pressure of a patient's arm to the blood pressure of the patient's leg. A healthy ABI is 0.9 or greater. In a study, researchers obtained the ABIof 187 women with arterial disease. The results were a mean ABI of 0.87 with a standard deviation of 0.16. At the 10% significance level, do the data provide sufficient evidence to conclude that,on average, women with arterial disease have an unhealthy ABI?Set up the hypotheses for the one-mean t-test.Ho: HHa: HThe test statistic is t=(Round to two decimal places as needed.)The P-value is(Round to three decimal places as needed.)the null hypothesis.

In a test of the effectiveness of garlic for lowering cholesterol, 64 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes (before minus after) in their levels of LDL cholesterol (in mg/dL) have a mean of 0.4 and a standard deviation of 23.9. Use a 0.05 significance level to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the garlic treatment? Assume that a simple random sample has been selected.
