An advertised average fuel consumption for a 2013 Land Rover LWB is 12 MPG (City). You choose a 0.05 signicance level to perform a hypothesis test to verify this claim using your brand new Land Rover. You record your fuel consumption and record the averages for every month. After 16 months you have a sample consisting of 16 data points: 14.61, 8.60, 11.85, 10.13, 15.26, 17.16, 18.77, 15.01, 9.21, 17.20, 16.22, 15.54, 11.81, 13.94, 9.36, 10.71.

(a) Set the signicance level to = 0:05 and use the null hypothesis signicance test to verify that the actual average fuel consumption is 12 MPG.

(b) Find the p-value corresponding to the given sample.

(c) Using the p-value from (b), nd the smallest signicance level that would lead to the rejection of the null hypothesis.
