Please solve using the 5 steps, thank you. Oil wells in a large field produce an average of 3.5 barrels per day. Fifteen randomly selected oil wells produce an average of 30 barrels of crude oil per day with a standard deviation of 3.5 barrels. Is this enough evidence to conclude that the oil wells are not producing an average of 33.5 barrels of crude oil per day? Test at a = 0.1. Use a two-tailed test.
