Researchers obtained the ankle brachial index (ABI), which compares ankle to arm blood pressures, of 187 women with peripheral arterial disease. A normal, healthy ABI, is 0.9 or greater. The sample had a mean ABI of 0.81 with a standard deviation of 0.15. At the 1% significance level, do the data provide sufficient evidence to conclude that, on average, women with peripheral arterial disease have an unhealthy ABI? Ho Ha to= Use the following abbreviated table IV to find the critical value, use the df which is closest to the df for the question. df 10.1 10.05 10.025 10.01 10.005 100 1.290 1.660 1.984 2.364 2.626 200 1.286 1.653 1.972 2.345 2.601 300 1.284 1.650 1.968 2.339 2.592 Critical value: Reject Ho?

Iron intakes were obtained during a 24-hour period for 45 randomly selected adult females under the age of 51 with a mean of 14.68 mg and a population standard deviation of 4.2. At the 1% significance, do the data suggest that adult females under the age of 51 are, on average, getting less than the RDA of 18 mg of iron? E-stat: (2 decimal places) =-critical: Reject Ho?
