A researcher is interested in finding a 95% confidence interval for the mean number minutes students are concentrating on their professor during a one hour statistics lecture. The study included 146 students who averaged 34.6 minutes concentrating on their professor during the hour lecture. The standard deviation was 13.2 minutes. Round answers to 3 decimal places where possible. a. To compute the confidence interval use at distribution. OF b. With 95% confidence the population mean minutes of concentration is between and minutes. c. If many groups of 146 randomly selected members are studied, then a different confidence percent of these confidence interval would be produced from each group. About 95 intervals will contain the true population mean minutes of concentration and about 5 percent will not contain the true population mean minutes of concentration.
