a. Construct the 99% confidence interval for the
difference between the population proportions. (Negative
values should be indicated by a minus sign. Round intermediate
calculations to at least 4 decimal places and final answers to 2
decimal places.)
a. Solution :
=> Answer :- The 99% confidence interval for the difference between the population proportions is -0.28 < p < -0.13
