Question 1
It is desired to test
H0:
μ = 55 against
Ha:
μ < 55 using
α = .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 50, what is the power of this test?

Question 2
It is desired to test H
0: μ = 50 against H
A: 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 45, what is the power of the test?
