The mean resting pulse rate for men is 72 beats per minute. a simple random sample of men who regularly work out at mitch's gym
tamaranim1 [39]

Claim: the mean resting pulse rate for men is less than 72 bpm.

Symbolic form would be: μ < 72

Step 1: null hypothesis  : μ > =  7 2 b p m

Step 2: alternative hypothesis:  μ <  7 2 b p m



Step 3: the test statistic is z = mean – μ / standard dev/sqrt (n) = -3/4 / 1.7639 = -1.92


Step 4: c v method: since z α = -1.645, the test static is z = -1.92 is less than the CV, we reject null hypothesis


            P Value method: area is 0.0274, since the p value is <= α, reject null hypothesis.

Step 5: the sample data support the claim that the mean resting pulse rate for men is less than 72 bpm.
