    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.
