3. Use the given degree of confidence and sample data to find the margin of error E and the confidence interval for the population mean µ. Salaries of statistics professors:

95% confidence; n=60, x = $85,678, s=$12,345. b. Times between uses of a TV remote control by males during commercials:99% confidence; n = 150, x= 7.60 sec, s = 2.72 sec. c. Distance driven by male students in one year: confidence; n= 100, x =11.878mi, s = 3577 mi. d. A sample of 35 skulls is obtained for Egyptian males who lived around 1850B.C. The maximum breadth of each skull is measured with the result that x =134.5 mm, and s=3.48 mm. Using these sample results and a confidence level of 95%. Calculator display is shown as: ZInterval (133.35, 135.65)X= 134.5 n= 35. Write a statement that interprets the confidence interval.
