Suppose you read in your local newspaper that 45 officials in student services earn an average of $50,340 each year. Assume that the standard deviation is $10,780 for salaries of college officials and student services. Find a 90% confidence interval for the population mean salaries of such personnel. Round your answer to the nearest dollar and don;t forget to use the $ sign.

Since sample size is > 40, we use the z-score in calculating for the confidence interval. The formula is given as: Confidence Interval = X ± z * σ / sqrt (n) Where, X = mean = $50,340 z = z-score which is taken from standard distribution tables at 90% …
