D Question 11 6 pts According to WHO, adolescents should spend at least an hour per day of moderate-to-vigorous intensity physical activity and should limit the time spent being sedentary. Based on this recommendation, a researcher wanted to estimate the mean sedentary time (sitting while watching TV, in a car, or while playing gadgets) of adolescents at 95% confidence level. In the study, a random sample of 25 adolescents spent an average of 8.76 hours per day being sedentary. Suppose that sedentary times are normally distributed with a standard deviation of 1.75 hour per day.
