An energy company wants to choose between two regions in a state to install energy-producing wind turbines. A researcher claims that the wind speed in Region Ais less than the wind speed in Region B. To test the regions, the average wind speed is calculated for 90 days in each region. The mean wind speed in Region A is13.9 miles per hour. Assume the population standard deviation is 2.9 miles per hour. The mean wind speed in Region B is 15.3 miles per hour. Assume thepopulation standard deviation is 3.1 miles per hour. At a = 0.05, can the company support the researcher's claim? Complete parts (a) through (d) below.O B. The wind speed in Region A is not less than the wind speed in Region B.O C. The wind speed in Region A is the same as the wind speed in Region BD. The wind speed in Region A is less than the wind speed in Region B.Let Region A be sample 1 and let Region B be sample 2. Identify Ho and HaHo: H1 2 H2Hai H1 < H2(b) Find the critical value(s) and identify the rejection region.The critical value(s) is/are z, =(Round to two decimal places as needed. Use a comma to separate answers as needed.)

In a certain population, triglyceride levels are approximately normally distributed with a mean of 150 mg/DL and a standard deviation of 42 mg/DL. Health experts define a level of 200 mg/DL or more as being high (and unhealthy, presumably). What percentage of this population would be considered to have an unhealthy triglyceride level?
