You are interested in finding a 95% confidence interval for the mean number of hours thatcollege students spend on line each day. The data below show the results of a survey of 16college students.2,3,1,4,0,8,2,3,1,1,6,9,3,1,0,5Assume a normal distribution and round your answers to two decimal places.A. To compute the confidence interval, use the [Select]distribution.B. With 95% confidence the population mean number of hours per day that college studentsspend on line is between [Select]and [Select]hours.C. If many groups of 16 randomly selected college students are surveyed, then a differentconfidence interval would be produced from each group. About[Select]percent of these confidence intervals will contain the truepopulation mean number of on line hours per day and about [Select]percent will not contain the true population mean number of on line hours per day.
