The level of nitrogen oxides (nox) in the exhaust of cars of a particular model varies normally with standard deviation σ=0.05grams per mile (g/mi). government regulations call for nox emissions no higher than 0.3 g/mi. in testing h0 : μ=0.3versus ha : μ< 0.3using significance level 0.05, we find that the power of this test against an alternative of μ=0.28 based on a random sample of size n = 40 is 0.808.using a larger sample size (n = 50) would select one: a. increase the power of this particular test. b. decrease the power of this particular test. c. increase the probability of a type i error. d. decrease the probability of a type i error.
