Answer:
The answer is "Option E".
Step-by-step explanation:
In order to find the contribution needed, we must use Chi-Square test statistics here.
Chi-square [tex]= \Sigma [\frac{(O -E)^2}{E}][/tex]
Here frequencies O are observed or frequencies E are expected.
Please find the calculation in the attached table.
Hence the contribution Chi-square is the highest for the vegetarian.
The value of its contribution to the appropriate test statistic the greatest is Vegetarian. The correct option is E.
It is a measure of the difference between the observed and expected value or frequency of the outcomes of a set of event variables.
The manager of a restaurant tracks the types of dinners that customers order from the menu correct amount of food is ordered from the supplier each week. Data from customer orders last weekly distribution.
Type of Dinner Beef, Chicken, Fish, Pork, and Vegetarian

Type of Dinner Beef, Chicken, Fish, Pork, and Vegetarian
Frequency 32 86 34 30 18
The table is shown below.
The value of its contribution to the appropriate test statistic the greatest is Vegetarian. The correct option is E.
