A smoking researcher is determining if the average age when smoking begins has changed in the last 40 years. She knows that the average age in 1980 was μ = 16.8 years (σ = 3 years). She asks a random sample of current smokers (n = 36) when they began smoking and she determined their mean to be M = 15.8 years. If we use p < .05 as the criterion for statistical significance, match all the responses below to determine the p-value under the null hypothesis.
