In a study of speed dating, male subjects were asked to rate the attractiveness of their female dates, and a sample of the results is listed below (1 = not attractive; 10 = extremely attractive). Construct a confidence interval using a 99% confidence level. What do the results tell about the mean attractiveness ratings of the population of all adult females? 6, 7, 2, 9, 6, 4, 7, 9, 8, 10, 5, 8 O What is the confidence interval for the population mean µ? <µ< (Round to one decimal place as needed.)
