Recent research suggests that children with ADHD tend to watch more TV than children who are not diagnosed with the disorder. To examine this relationship, a researcher obtains a random sample ofn=36 children aged 8-12 yrs old who have been diagnosed with ADHD. Each child is asked to keep a journal recording how much time they spend watching TV. The average daily TV time in the sample is 4.9 hours. It is known that in the population of 8-12 yr old children, u = 4.1 hrs, o = 1.8, and is normally distributed. Are the data sufficient to conclude that children with ADHD watch significantly more TV than children without the disorder? Use an a = .05. Step 1: Which of the following correctly represents the null and alternative hypothesis for the mentioned sample of n =36

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.
