STATISTICS

Identify what statistic tool should be used and solve.

A popular cooling method for a gas turbine engine uses high-pressure inlet fogging. The performance of a sample of 67 gas turbines augmented with high-pressure inlet fogging was investigated in the Joumal of Engineering for Gas Turbines and Power (Jan. 2005). One measure of performance is heat rate (kilojoules per kilowatt per hour). Heat rates for 67 gas turbines are listed in the table below. Suppose that a standard gas turbine has, on average, a heat rate of 10,000 kak'th. ---------- Conduct a test to determine whether the mean heat rate of gas turbines augmented with high-pressure inlet fogging exceeds 10,000 kak'Nh. Use or = 0.05
