A random sample of 250 bolts from machine A contained 17 defective bolts, while an independently chosen, random sample of 400 bolts from machine B contained 32 defective bolts. Let p, be the proportion of the population of all bolts from machine A that are defective, and let p, be the proportion of the population of all bolts from machine B that are defective. Find a 99% confidence interval for p,-p2. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your responses to at least three decimal places. (If necessary, consult a list of formulas.) What is the lower limit of the 99% confidence interval? What is the upper limit of the 99% confidence interval?

Chapter 6, Section 5, Exercise 235 Use a t-distribution to find a confidence interval for the difference in means μd=μ1-μ2 using the relevant sample results from paired data. Assume the results come from random samples from populations that are approximately normally distributed, and that differences are computed using d=x1-x2.A 95% confidence interval for μd using the paired data in the following table: Case Situation 1 Situation 2 1 76 86 2 81 85 3 94 91 4 61 77 5 70 78 6 71 60 7 85 89 8 89 90 Give the best estimate for μd, the margin of error, and the confidence interval.Enter the exact answer for the best estimate, and round your answers for the margin of error and the confidence interval to two decimal places.best estimate = Enter your answer; best estimatemargin of error = Enter your answer; margin of errorThe 95% confidence interval is Enter your answer; The 95% confidence interval, value 1 to Enter your answer; The 95% confidence interval, value 2.

Statistics Question
A statistician wanted to construct a 95% confidence interval for the population slope between height (in inches) and weight (in pounds) of his co-workers. He made height the explanatory (independent) variable and weight the response (dependent) variable. He selected a random sample of 30 people from work and asked them to list their height and weight. After seeing his conditions were satisfied, he constructed the interval. Which of the following would he use for the critical value? A) 1.960 B) 2.037 C) 2.042 D) 2.045 E) 2.048
