Consider the following results for independent samples taken from two populations.
Develop a 95% confidence interval for the difference between the two population proportions.
a. (0.13 to 0.29)
b. (0.05 to 0.19)
c. (0.09 to 0.21)
d. (0.06 to 0.18)
Sample sizes are large so we will use critical value using normal table for calculating confidence interval.
