In 2010, a survey of 2000 homes in a region found that 200 had overestimated market values. Suppose you want to estimate "I" , the population proportion of homes in this region with market values that are overestimated. a. Find p, the point estimate of I. b. Describe the distribution used to find the critical value. c. Find a 90% confidence interval for It. d. Give a practical interpretation of the confidence interval from part c. e. Suppose a researcher claims that it = 0.06. Is the claim believable? Explain. . . . a. The point estimate is . (Type an integer or a decimal.) b. We use the t-distribution to find the critical value for the confidence interval of a proportion. O True O False c. The 90% confidence interval is ( (Round to two decimal places as needed.)d. Interpret the confidence interval. One can be % confident that the interval contains the true value of the population proportion It e. Is the claim that It = 0.06 believable? O A. Yes. This proportion is within the limits of the confidence interval. O B. Yes. This proportion is within three standard deviations of the sample mean. O C. No. This proportion is beyond three standard deviations of the sample mean. O D. No. This proportion is below the lower limit of the confidence interval
