Question

you have...
(a) 2 samples
(b) independent samples
(c) involving proportions
(d) is a confidence interval
what test would you run (number on the calculator sheet/overview sheet)?
○#9: confidence interval for one population mean (t - interval) σ unknown
○#10: hypothesis test (2 - prop z - test) & confidence interval (2 - prop z interval) for two population proportions
○#11: hypothesis test for paired t - test (t - test on differences) & confidence interval for the differences in means from paired samples (t interval on list of differences)
○#12: hypothesis test (2 - sample t - test) & confidence interval (2 - sample t interval) for independent samples for two means

Explanation:

We have 2 independent samples involving proportions. The appropriate test for this situation is the Hypothesis Test (2 - Prop Z - Test) & Confidence Interval (2 - Prop Z Interval) for Two Population Proportions.

Answer:

#10: Hypothesis Test (2-Prop Z-Test) & Confidence Interval (2-Prop Z Interval) for Two Population Proportions
