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 critical value method of testing hypotheses. 69 68 59 49 62 74 62 48 50 65 74 58 Enter the smallest critical value. (Round your answer to nearest thousandth.)
