A simple random sample of 90 is drawn from a normally distributed

A simple random sample of 90 is drawn from a normally distributed population, and the mean is found to be 138, with a standard deviation of 34. What is the 90% confidence interval for the population mean? Use the table below to help you answer the question. Confidence Level z*-score 90% 1.645 95% 1.96 Z S Remember, the margin of error, ME, can be determined using the formula ME= O 128.75 to 147.25 O 130.98 to 145.02 O 132.10 to 143.90 O 137.38 to 138.62 99% 2.58
