At issue is the proportion of people in a particular county who do not have health care insurance coverage and an investigator wants to estimate it with 90% confidence. A preliminary sample of 230 people were asked if they have insurance coverage and 57 replied that they did not have coverage. What sample size would be needed to achieve a margin of error of .03? 0 752 561 There is not enough information to answer this question. 0 796 561The Loan Data worksheet of the Exam 2 Data.xisx file contains a subset of data from a Kaggle data science competition. The data are from Lending Club and "contain ... loan data for ... loans issued [between] 2007-2015, including the current loan status (Current, Late, Fully Paid, etc.) and latest payment information." This question is about the variable "Interest Received," which is the the amount of interest received to date. Suppose that historically the mean interest received for the population from which the sample was taken has been $2,767. Use the appropriate hypothesis test to determine if there is evidence in the data to conclude that the mean value has decreased at the 0.10 level of significance. What is your conclusion? O Because the p-value is .2774, we should reject the null hypothesis and conclude there is enough evidence to say that the mean amount of interest received has decreased. Because the p-value is .1387, we should not reject the null hypothesis and conclude there is not enough evidence to say that the mean amount of interest received has decreased. Because the p-value is .8613, we should not reject the null hypothesis and conclude there is not enough evidence to say that the mean amount of interest received has decreased. Because the p-value is .8613, we should reject the null hypothesis and conclude there is enough evidence to say that the mean amount of Interest received has decreased. Because the p-value is .1387, we should reject the null hypothesis and conclude there is enough evidence to say that the mean amount of Interest received has decreased. Because the p-value is 2774, we should not reject the null hypothesis and conclude there is not enough evidence to say that the mean amount of Interest received has decreased,The theoretical, true but unknown spread in sample means or averages is the population standard deviation. the estimated standard error. the sample standard deviation. the (true) standard error.
