Q:

1- A study of 200 males versus 200 females mean blood pressure scores. The mean blood pressure for females is 110 with a standard deviation of 9 and for males, the mean blood pressure score is 125 with a standard deviation of 12.

Form a 95% confidence interval for the mean blood pressure for females and males. (Z score=1.96)

2-A study was done on the proportion of males and females who participate in athletics. 490 females and 540 males participated in the study, where 160 females and 215 males participated in athletics

Form a 95% CI for each of the proportion of female and male athletes (Z score=1.96)
