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.

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
