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? 7, 7, 3, 10, 7, 5, 8, 9, 7, 9, 3,9 What is the confidence interval for the population mean ? 4.8 << 9.2 (Round to one decimal place as needed.) What does the confidence interval tell about the population of all adult femalles? Select the correct choice bellow and, if necessary, fill in the answer box(es) to complete your choice. OA. We are confident that 99% of all adult females have attractiveness ratings between and (Round to one decimal place as needed.) OB. The results tell nothing about the population of all adult females, because participants in speed dating are not a representative sample of the population of all adult females OC. We are 99% confident that the interval from 10 actually contains the true mean attractiveness rating of all adult females (Round to one decimal place as needed.)

OA. We are confident that 99% of all adult females have attractiveness ratings between and
(Round to one decimal place as needed.)
OB. The results tell nothing about the population of all adult females, because participants in speed dating are not a representative sample of the population of all adult females
OC. We are 99% confident that the interval from to actually contains the true mean attractiveness rating of all adult females
(Round to one decimal place as needed.)
