Set up the hypothesis for the one mean t test

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 ABI of 187 women with arterial disease. The results were a mean ABI of 0.87 with a standard deviation of 0.13. At the 10% significance level, do the data provide sufficient evidence to conclude that, on average, women with arterial disease have an unhealthy ABI?
