Table 3. Data Population Standard Deviation Desired Sampling Error/confidence interval Confidence Level Intermediate Calculations ZValue Calculated Sample Size Result Sample Size Needed Instructions To improve the estimate of the population, the creditors want to know how big of a sample size is required to obtain a confidence interval that is within +/- 5 points of the population. (1) Complete Table 3 to determine what sample size is required to have a 95% confidence interval with a sampling error of 5. Assume the population standard deviation = 25.44. SHOW ALL WORK
