A simple random sample of men who regularly work out at Mitch's Gym is obtained and their resting pulse rates (in beats per minute) are listed below. Use a 0.1 significance level to test the claim that these sample pulse rates come from a population with a mean less than 72 beats per minute (the mean resting pulse rate for men). Use the p-value method of testing hypotheses.

54 54 51 58 56 74 66 74 59 52 56 73

Enter the test statistic. (Round your answer to nearest hundredth.)
