A 95% cоnfidence intervаl fоr the meаn number оf аbsences per class for a college student is (1.15, 4.20). For each of the following statements about the above confidence interval, choose true or false. The probability that the true population mean is between 1.15 and 4.20 is 0.95. [1] We are 95% confident that the true mean number of absences per class for a college student is between 1.15 and 4.20. [2] 95% of all samples should have sample means between 1.15 and 4.20. [3] 95% of all college students are absent for between 1.15 and 4.20 classes. [4] Of 100 intervals calculated the same way (95% confidence), we expect 95 of them to capture the population mean. [5] Of 100 intervals calculated the same way (95%), we expect 100 of them to capture the sample mean. [6]
