A Random Group of Customers at a Fast Food Chain $50 \%$

question 16

Multiple Choice

A random group of customers at a fast food chain were asked whether they preferred hamburgers, chicken sandwiches, or fish sandwiches. The restaurant's marketing department claims that $50 \%$ of customers prefer hamburgers, $32 \%$ of the customers prefer chicken sandwiches, and $18 \%$ of the customers prefer fish sandwiches. Is there evidence to reject this hypothesis at $\alpha = 0.05$ ?
$\begin{array} { l c c c } \text { Plans } & \text { Hamburgers } & \text { Chicken } & \text { Fish } \\ \text { Number of students } & 40 & 20 & 6 \end{array}$

• A) There is not evidence to reject the claim that the customers' preferences are distributed as claimed because the test value 4.455 < 7.815
• B) There is evidence to reject the claim that the customers' preferences are distributed as claimed because the test value 7.815 > 4.455
• C) There is not evidence to reject the claim that the customers' preferences are distributed as claimed because the test value 4.455 < 5.991
• D) There is evidence to reject the claim that the customers' preferences are distributed as claimed because the test value 5.991 > 4.455

F-ratio

A statistic used to compare the variance among group means in an analysis of variance (ANOVA) test.

P-value

A function of the observed sample results in a statistical hypothesis test, representing the probability of obtaining test results at least as extreme as the results actually observed, under the assumption that the null hypothesis is correct.
