Construct a 90% confidence interval of the mean pulse rate for adult males. nothing bpmless thanmuless than nothing bpm (Round to one decimal place as needed.) Compare the results. 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 do not overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males. C. The confidence intervals overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males. D.

A physician wants to develop criteria for determining whether a
patient's pulse rate is atypical, and she wants to determine
whether there are significant differences between males and
females. Use the sample pulse rates below.
