Question 1

It is desired to test H0: μ = 50 against HA: μ ≠ 50 using α = 0.10. The population in question is uniformly distributed with a standard deviation of 15. A random sample of 49 will be drawn from this population. If μ is really equal to 48, what is the probability that the hypothesis test would lead the investigator to commit a Type II error?
◦ 0.8994
◦ 0.1006
◦ 0.2433
◦ 0.7567

Question 2

It has been estimated that the G-car obtains a mean of 40 miles per gallon on the highway, and the company that manufactures the car claims that it exceeds this estimate in highway driving. To support its assertion, the company randomly selects 64 G-cars and records the mileage obtained for each car over a driving course similar to that used to obtain the estimate. The following data resulted: = 41.5 miles per gallon, s = 8 miles per gallon. Calculate the value of β if the true value of the mean is 42 miles per gallon. Use
