Applet Exercise Refer to Exercises 8.518.53. Change the value of p to .90. Change the sample size to n = 10 and the confidence coefficient to 0.95. Click the button 100 Samples a few times. After each click, write down the number of intervals that captured p = .90. a When the simulation produced ten successes in ten trials, what is the resulting realized 95% confidence interval for p? What is the length of the interval? Why? How is this depicted on the display? b How many intervals did you generate? How many of the generated intervals captured the true value of p? c What percentage of all of the generated intervals captured p? d Does the result of part (c) surprise you? e Does the result in part (c) invalidate the large-sample confidence interval procedures presented in this section? Why?
