Textbook Question

Chapter 10.3, Problem 15P

Basic Computation: Confidence Inters al for p 1 − p 2 Consider two independent binomial experiments. In the first one. 40 trials had 10 successes. In the second one. 50 trials had 15 successes.

(a)Check Requirements Is it appropriate to use a normal distribution to approximate the p ^ 1 − p ^ 2 distribution ? Explain.

(b) Find a 95% confidence interval for p 1 − p 2 .

(c)Interpretation Based on the confidence interval you computed, can you be 95% confident that p 1 is more than p 2 ? Explain.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
