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?Sample ratings: 7, 9, 3, 8, 5, 4, 8, 7, 10, 5, 9**Question: What is the confidence interval for the population mean μ?**[ ] < μ < [ ] (Round to one decimal place as needed.)**Question: What does the confidence interval tell about the population of all adult females?
