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.

It can be confusing because it isn't specific enough. In astronomy, the big dipper is not a spoon. It is a bear. Scientists know it as Ursa Major rather than a dipper or bear.
