A.


The confidence intervals do not​ overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.









B.


The confidence intervals​ overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.









C.


The confidence intervals​ overlap, so it appears that adult males have a significantly higher mean pulse rate than adult females.








D.


The confidence intervals do not​ overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males.
