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 150 students who averaged 32.8 texts per day. The standard deviation was 19.3 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 times per day that college students text is between _____ and ______ times c. If many groups of 149 randomly selected members are studied, then a different confidence interval would be produced from each group. About _____percent of these confidence intervals will contain the true population number of texts per day and about_________ percent will not contain the true population number of texts per day.
