Refer to the accompanying data set and construct a 90​%confidence interval estimate of the mean pulse rate of adult​females; then do the same for adult males. Compare the results.

Construct a 90​% confidence interval of the mean pulse rate foradult females.
___ bpm < mu < ___ bpm
​(Round to one decimal place as​ needed.)
Construct a 90​% confidence interval of the mean pulse rate foradult males.
___ bpm < mu < ___ bpm (Round to one decimal place as​needed.)
Compare the results.
A. The confidence intervals do not​ overlap, so it appears thatadult females have a significantly higher mean pulse rate thanadult males.
B. The confidence intervals​ overlap, so it appears that adultmales have a significantly higher mean pulse rate than adultfemales.
C. The confidence intervals​ overlap, so it appears that thereis no significant difference in mean pulse rates between adultfemales and adult males.
D. The confidence intervals do not​ overlap, so it appears thatthere is no significant difference in mean pulse rates betweenadult females and adult males.
