Question

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 0.02 level of significance. The researcher checks 34 smokers and finds that they have a mean pulse rate of 76, and 43 non-smokers have a mean pulse rate of 74. The standard deviation of the pulse rates is found to be 6 for smokers and 10 for non-smokers. Letu be the true mean pulse rate for smokers and H2 be the true mean pulse rate for non-smokers. Step 3 of 4: Determine the decision rule for rejecting the null hypothesis Ho. Round the numerical portion of your answer to two decimal places. Tables Keypad Answer Previous Step Answers Reject H if

Explanation / Answer

we know that

if p value is less than alpha , then we reject the null hypothesis in favor of alternate hypothesis

if p value is greater than alpha , then we FAIL to reject the null hypothesis in favor of alternate hypothesis

as the signficane level is given as 0.02 , so if the p value is less than 0.02 , then we reject the null hypothesis

Reject H0 is p value is less than 0.02
