1. The heart beats of ordinary males follow a normal distribution with mean 75 per minute and standard deviation 3. To test whether certain treatment is effective in restoring the heart beats of patients, ten patients after the treatment were randomly selected and their heart beats per minute are 71, 65, 80, 81, 76, 79, 78, 87, 63, 82. Test the hypothesis at significance level 0.05.

Step 1

e., the mean heart beats after treatment is still 75 per minute. - Alternative hypothesis (H1): The treatment is effective in restoring the heart beats of patients, i.e., the mean heart beats after treatment is different from 75 per minute. Show more…
