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 A is less than the wind speed in Region B.To test the regions, the average speed is calculated for 60 days in each region.The mean wind speed in Region A is 14.0 miles per hour. Assume the standard deviation is 2.9 miles per hour.The mean wind speed in Region B is 15.1 miles per hour.Assume the population deviation is 3.3 miles per hour. .At = 0.05, can the company support the researcher's claim?
