Score: 7.6/14 8/14 answered Question 14 0/1 pt A psychiatrist is interested in finding a 90% confidence interval for the tics per hour exhibited by children with Tourette syndrome. The data below show the tics in an observed hour for 10 randomly selected children with Tourette syndrome. 4 0 11 5 6 5 1 11 10 3 a. To compute the confidence interval use a ? ~| distribution. b. With 90% confidence the population mean number of tics per hour that children with Tourette syndrome exhibit is between and days . c. If many groups of 10 randomly selected children with Tourette syndrome are observed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population mean number of tics per hour and about percent will not contain the true population mean number of tics per hour.

If many groups of 11 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About percent of Ive these confidence intervals will contain the true population mean number of missed class days and about percent will not contain the true population mean number of missed class days.
