researcher plans a study in which a crucial step is offering participants a food reward. It is important that the three food rewards be equal in appeal. Thus, a pre-study was designed in which participants were asked which of the rewards they preferred Of the 60 participants, 16 preferred cupcakes, 26 preferred candy bars, and 18 favore dried apricots. Do these scores suggest that the different foods are differentially preferred by people in general? e the .05 significance level) ao pointso

Explanation / Answer

Ans: We will perform Chi square test of independence for this.

Null Hypothesis H0: If all foods choices to be equally likely

Alternate hypothesis HA: If all foods choices are not equally likely.

Calculated chi square score=2.8

p-value for chi score of 2.8 and df=3-1=2 is 0.247

As,p-value>0.05,we can not reject the null hypothesis that is all food choices are equally likely or foods are not differentially preferred.

Group Observed count(O) Expected count(E) (O-E)^2/E Cup cake 16 20 0.8 candy bars 26 20 1.8 apricot 18 20 0.2 60 60 2.8
