A psychiatrist is interested in finding a 98% confidence interval for the tics per hour exhibited by children with Tourette syndrome. The data below show the tics in an observed hour for 12 randomly selected children with Tourette syndrome. Round answers to 3 decimal places where possible. 10 4 3 4 9. 12 2 3 10 12 a. To compute the confidence interval use a v? fistribution. b. With 98% confidence the population mea ber of tics per hour that children with Tourette syndrome exhibit is between and c. If many groups of 12 randomly selected children with Tourete 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. 6
