A medical researcher wants to compare the pulse rates of smokers
and non-smokers. He believes that the pulse rate for smokers and
non-smokers is different and wants to test this claim at
the 0.10.1 level of significance. The researcher
checks 3535 smokers and finds that they have a mean pulse
rate of 7676, and 4949 non-smokers have a mean pulse
rate of 7474. The standard deviation of the pulse rates is
found to be 66 for smokers and 99 for
non-smokers. Let μ1μ1 be the true mean pulse rate for
smokers and μ2μ2 be the true mean pulse rate for
non-smokers.
Step 1 of 4:
State the null and alternative hypotheses for the test.
Step 2 of 4:
Compute the value of the test statistic. Round your answer to
two decimal places.
Step 3 of 4:
Determine the decision rule for rejecting the null
hypothesis H0H0. Round the numerical portion of your answer to
three decimal places.
Step 4 of 4:
Make the decision for the hypothesis test.
