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 11 randomly selected children with Tourette syndrome. Round your decimal 3 places. 1,12,11,6,10,1,4,7,8,1,9 With 98% confidence the population mean number of tics per hour that children with Tourette syndrome exhibit is between ____ and ____ If many groups of 11 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.
