Math Problem Statement
Recall that the cigarette industry requires that models in cigarette ads must appear to be at least 25 years old. Also recall that a sample of 50 people is randomly selected at a shopping mall. Each person in the sample is shown a "typical cigarette ad" and is asked to estimate the age of the model in the ad. The p-value for testing H0 versus Ha can be calculated to be 0.0044. Determine whether H0 would be rejected at each of α = .10, α = .05, α = .01, and α = .001. (Round your answer to 4 decimal places.)
