Refer to the accompanying data set and construct a 9090% confidence interval estimate of the mean pulse rate of adult females;
then do the same for adult males. Compare the results. Loading... Click the icon to view the pulse rates for adult females and adult males. Construct a 90% confidence interval of the mean pulse rate for adult females. 71.8 bpm < μ< 79.0 bpm Construct a 90% confidence interval of the mean pulse rate for adult males. 63.3 bpm < μ 69.9 bpm. 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 adult males have a significantly higher mean pulse rate than adult females.
D. The confidence intervals overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.
Division is repeated subtraction, just like multiplication is repeated addition. If you divide 50 by 10, you get 5. This is also the question: How many times do you have to subtract 10 from 50 to get 0?
