The study included 150 students who averaged 32.3 minutes concentrating on their professor during the hour lecture. The standard deviation was 11.8 minutes. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a |? distribution. b. With 95% confidence the population mean minutes of concentration is between and minutes. c. If many groups of 150 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 mean minutes of concentration and about percent will not contain the true population mean minutes of concentration.
