A researcher is interested in finding a 95% confidence interval for the mean number of times per day that college students text. The study included 107 students who averaged 29.1 texts per day. The standard deviation was 18.2 texts. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a ? ✓ distribution. b. With 95% confidence the population mean number of texts per day is between texts. and c. If many groups of 107 randomly selected members are studied, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain percent will not contain the true the true population number of texts per day and about population mean number of texts per day.
