A researcher wants to make a ninety-five percent confidence interval for the population mean. She wants the margin of error of estimate (precision) to be within 0.56 of the population mean. The population variance is 7.6. The sample size that will yield a margin of error of estimate within 0.56 of the population mean is: O d. n = 94. O b. n = 708. a. n = 10. O c. n = 25. O e. n = 30.
