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

Hence from the given value male and female.

From this confidence intervals do not overlap so adult females have higher rate than adult males.

Step-by-step explanation:

Taking mean for female =    3025 / 40  = 75.6

taking mean for male = 2666/40 =66.65

Construction of hypothesis:

For 90 % confidence interval for adult female :

72.0 bpm <μ<75.2 bpm

For 90 % confidence interval of adult females:

66.65 bpm<μ<70.6 bpm

From this confidence intervals do not overlap so adult females have higher rate than adult males.
