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.
