The u. s. department of health and human services collected sample data for 772 males between the ages of 18 and 24. that sample group has a mean height of 69.7 inches with a standard deviation of 2.8 inches. find the 99% confidence interval for the mean height of all males between the ages of 18 and 24.

(69.44, 69.96).

Step-by-step explanation:

Given : Sample size : n= 772

Significance level :

Critical value :

Sample mean :

Standard deviation:

The confidence interval for population mean is given by :-

i.e

i.e

Hence, the confidence interval for the mean height ( in inches) of all males between the ages of 18 and 24 is (69.44 , 69.96).

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
