What Proportion of Americans Say They Are Poor? A survey of 1000 US Adults conducted in October 2019 found that 182 of them described themselves as poor. In Exercise 3.128, we used a bootstrap distribution to find a 90% confidence interval for the proportion of all US adults who would describe themselves as poor. Here, we find this 90% confidence interval using the normal distribution and a formula for the standard error, as follows:

(a) Give value for the sample statistic.
Value = .

(b) Find the standard error for this sample statistic. Round to three decimal places.

(d) Use the results of (a), (b), and (c) to find the 90% confidence interval. Round to three decimal places.
