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 14 randomly selected children with Tourette syndrome. Round answers to 3 decimal places where possible. 11 3 3 4 7 4 6 10 7 5 9 10 7 8 b. With 98% confidence the population mean number of tics per hour that children with Tourette syndrome exhibit is between ?and ? c. If many groups of 14 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.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

c. If many groups of 14 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.
