-What are the degrees of freedom? (choose from below)

49 47 45 48

  

 -  What is the correct decision for this test?(choose from below)

Since p-value < 0.05, reject H0
Since p-value > 0.05, reject H0
Since p-value < 0.05, do not reject H0
Since p-value > 0.05, do not reject H0

 

- An appropriate conclusion for this test is (choose from below)

-The first pulse rates of male students who did not run are significantly higher than the first pulse rates of female students who did not run on the spot

-The first pulse rates of male students who did not run are significantly lower than the first pulse rates of female students who did not run on the spot
-The first pulse rates of male students who did not run could be the same as the first pulse rates of female students who did not run
-The first pulse rates of male students who did not run are the same as the first pulse rates of female students who did not run

Expert Solution
Step 1

We have to answer the above questions using the given output as reference.

The output represents two sample t-test.

There is two independent samples which are males and females.

The hypothesis test is about whether there is a difference between pulse rates of males and females or not.

This is two-tailed test with unequal variances.

We have to find the degrees of freedom, decision and conclusion.
