A researcher is interested in finding a 9396 confidence interval for the mean number of times per dag.r that college students text. The stud}.I included '3'? students who averaged 33.1 texE per day. The standard deviation was 14.9 texts. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a distribution. b. With 93% confidence the population mean number of texts per day.r is between C] and c. If man}.r groups of 9? randomly.I selected members are studiedJ then a different confidence interval would be produced from each group. About :1 percent of these confidence intervals will contain the true population number of text per dayr and about :1 percent will not contain the true population mean number of texts per day
