No work needed, only correct solution:

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 6.3 years. At a = 0.08. is there enough evidence to reject the claim that the mean time it takes smokers to quit smoking permanently is 14 years?
