Suppose that local police are interested in determining whether the average speed of cars through a local intersection exceeds the local speed limit of 40 mph. They measure the speed (in mph) for a sample of 10 randomly selected cars passing through that intersection and collect the following data:

45, 59, 53, 50, 45, 49, 53, 38, 62, 73

Showing all necessary computations, conduct the most appropriate hypothesis test, at a = .05, to most effectively address whether the average speed of cars in this intersection exceeds 40 mph.

Provide the information indicated below:

a) What must you assume when applying the test in this case?

b) Statistical Hypotheses

c) Decision Rule

d) Calculations

e) Decision

f) Interpretation
