Question:

Basic Computation: Confi dence Interval for p1 p2 Consider two independent binomial experiments. In the fi rst one, 40 trials had 15 successes. In the second one, 60 trials had 6 successes.

(a) Check Requirements Is it appropriate to use a normal distribution to approximate the pˆ1 pˆ2 distribution? Explain.

(b) Find a 95% confi dence interval for p1 p2.

(c) Interpretation Based on the confi dence interval you computed, can you be 95% confi dent that p1 is more than p2? Explain.
