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.
