abA newspaper article reported that people spend a mean of 7 hours per day watching TV, with a standard deviation of 2.1 hours. A psychologist would like toconduct interviews with the 10% of the population who spend the most time watching TV. She assumes that the daily time people spend watching TV isnormally distributed. At least how many hours of daily TV watching are necessary for a person to be eligible for the interview? Carry your intermediatecomputations to at least four decimal places. Round your answer to one decimal place.JockeschoursExplanation!1QA1NCheck202WSXXcontrol option command3H#20EDS$4C900000F4RFer de%5VTG6B20F6YH&744F7UNⒸ2022 McGraw Hill LLC. All Rights Reserved.

Data from the Office for National Statistics show that the mean age at which men in Great Britain get married was 33.5. A news reporter noted that this represents a continuation of the trend of waiting until a later age to wed. A new sample of 47 recently wed British men provided their age at the time of marriage. These data are contained in the Excel Online file below. Construct a spreadsheet to answer the following questions. Open spreadsheet Do these data indicate that the mean age of British men at the time of marriage exceeds the mean age in 2013? Test this hypothesis at a = 0.05. What is your conclusion? Use the obtained rounded values in your calculations.
