The consumption rates of two aviation fuels, A and B, are compared. The sample from fuel A have 12 specimens with a mean burning rate of 21 cm/s and the sample from fuel B have 10 specimens with a mean burning rate of 18 cm/s. If the standard deviation in burning rates of the fuels are 3.5 cm/s and 3cm/s for fuel A and fuel B, respectively, test the hypothesis that the difference in mean burning rates of fuels is 2.5cm/s. Use ? = 0.05.
a. Use P-value approach for hypothesis testing.
b. Use z-test for hypothesis testing.
c. Use confidence interval for hypothesis testing.
d. If the true difference in the mean burning rates is ?2 ′ − ?1 ′ = 3 cm/s, find the type II error.
e. What is the minimum sample size needed to recognize the true mean burning rate of 3 cm/s for ? = 0.05, and ? = 0.05.

A fuel consumption study is conducted for two types of
automobiles. One representative vehicle of each type is selected,
and the mileage performance is observed for 10 tanks of fuel in
each car. The data obtained, expressed in miles per gallon (mpg),
are as follows:
Car 1: 24.7 24.9 24.8 24.6 24.9 23.9 24.7 24.9 24.5 24.6
Car 2: 41.7 42.8 42.3 42.4 41.6 39.9 39.5 40.8 41.9 39.6
