Answer:

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.
