Use chi square and test at the .05 level.
Solution
Total no of persons = 99
Set up hypotheses as
H0: All 3 steaks are equally likely
Ha: atleast two are not equally likely
Two tailed chi square test at 0.05 level
Prepare chi square table as follows:
p value =0.131296.
The result is not significant at p < 0.05.
Since p >alpha, accept null hypothesis.
| Place I | Place II | Place III | Total | |
| Observed | 35 | 40 | 24 | 99 |
| Expected | 33 | 33 | 33 | 99 |
| Chis quare | 0.121212 | 1.484848 | 2.454545 | 4.060606 |
