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.
The answer would be
