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.

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
