The lengths of time (in years) it took a random sample of 32 former smokers to quit smoking permanently are listed. Assume the population standard deviation is 5.3 years. At α = 0.08, is there enough evidence to reject the claim that the mean time it takes smokers to quit smoking permanently is 15 years?
