Question

Find the margin of error for a 95% confidence interval for estimating the population mean when the sample standard deviation equals 90, with a sample size of) 324 and () 1444. What is the effect of the sample size? () Find the margin of error for a 95% confidence interval for estimating the population mean when the sample standard deviation equals 90 with a sample size of 324 (Round to two decimal places as needed.) (1) Find the margin of error for a 95% confidence interval for estimating the population mean when the sample standard deviation equals 90 with a sample size of 1444 (Round to two decimal places as needed.) What is the effect of the sample size on the margin of error? Choose the correct answer below. OA The margin of error is the same for a sample sizes OB. The larger sample size decreases the margin of error, O C. The larger sample size increases the margin of error, OD. There is no correlation between the sample size and the margin of error
