Compute a 95% confidence interval for a sample of 50 items, where the mean was computed to be 20, and the population standard deviation is known to by 10. Solution: Note that since the population standard deviation is known we can use the “z” interval. Step1: make sure you are on the “confidence interval” worksheet (there are 3 worksheets)

49. A The 95% confidence interval for the population mean is. In this particular problem, we have. Using df = n – 1 = 4, we look up (in a table) that t.025 = 2.776. Then our confidence interval is. 50. C Assumptions for the confidence interval for the mean are as follows: data is quantitative, random sample, data comes from a normal distribution.
