Compare the results.

A.

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

B.

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.

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.

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

Answer #1

The statistical software output for this problem is:

Hence,

95% confidence interval of the mean pulse rate for adult females:

**71.4** bpm < <
**80.2** bpm

95% confidence interval of the mean pulse rate for adult males:

**63.2** bpm < <
**71.0** bpm

Compare: **Option D** is correct.

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.
