A researcher wanted to see whether there was a significant difference in resting pulse rates for men and women.

The data she collected is summarized to the right.

For both groups, the data appear to be unimodal and

symmetric. Is this evidence that resting pulse rates for men

are higher than for women?

Test an appropriate hypothesis using a

significance level of 0.10 (α = 0.10).

You can assume all conditions and assumptions are met.

a. Write the Hypothesis for the test.

4. Using the information given in question #3 above, create a 90% confidence interval for the difference in mean

resting pulse rates for men and women and interpret your interval in the context of the problem.
