Homework Answers
a. Here population standard deviation is 7
So we will use z distribution to find CI
z value for 99% CI is 2.576 as P(-2.576<z<2.576)=0.99
So Margin of Error is 
b. As data value is not give, so i will just keep 
for mean value, you can find value of mean for given sample and
complete the problem
So CI i
