Consider the following results for independent samples taken from two populations
Sample 1 Sample 2
n1 = 400...........n2 = 300
p1 = 0.48.........p2 = 0.36
a. What is the point estimate of the difference between the two population proportions?
b. Develop a 90% confidence interval for the difference between the two population proportions.
c. Develop a 95% confidence interval for the difference between the two population proportions.
