A psychiatrist is interested in finding a 90% confidence interval for the tics per hour exhibited bychildren with Tourette syndrome. The data below show the tics in an observed hour for 14randomly selected children with Tourette syndrome. Round answers to 3 decimal places wherepossible.8.9.39.101142121210a. To compute the confidence interval use adistribution.b. With 90% confidence the population mean number of tics per hour that children with Tourettesyndrome exhibit is betweenandc. If many groups of 14 randomly selected children with Tourette syndrome are observed, then adifferent confidence interval would be produced from each group. Aboutpercent ofthese confidence intervals will contain the true population mean number of tics per hour andaboutpercent will not contain the true population mean number of tics per hour.
