Listed below are student evaluation ratings of courses, where a rating of 5 is for "excellent." the ratings were obtained at one university in a state. construct a confidence interval using a 95% confidence level. what does the confidence interval tell about the population of all college students in the state? 3.6, 2.8, 4.1, 4.9, 3.1, 4.2, 3.6, 4.4, 4.3, 3.9, 4.6, 3.6, 3.5, 4.1, 3.8 what is the confidence interval for the population mean mu? 3.59less thanmuless than 4.21 (round to two decimal places as needed.) what does the confidence interval tell about the population of all college students in the state? select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. a. the results tell nothing about the population of all college students in the state, since the sample is from only one university. b. we are 95% confident that the interval from nothing to nothing actually contains the true mean evaluation rating. (round to one decimal place as needed.) c. we are confident that 95% of all students gave evaluation ratings between nothing and nothing. (round to one decimal place as needed.)
