The time spent, in minutes, on physical activities per day was recorded for a sample of college students. The 90% and 99% confidence intervals for the mean time spent on physical activities are (56.226, 60.174) and (55.109, 61.291). Which of the following would be a 95% confidence interval calculated from the sample data used to create the confidence intervals above? (56.473, 59.927) O (55.648, 60.352) O(54.832, 61.568) (55.848, 60.552)
