Category | Observed Frequency |
Expected Frequency |
A |
10 | |
B | 16 | |
C | 20 | |

E | 13 |
- Complete the table by calculating the expected frequencies.
- What is the chi-square test statistic? Round to three decimal places.
χ2=χ2= - What are the degrees of freedom?
d.f.= - What is the pp-value for this sample? Round to four decimal places.
pp-value = - Is the pp-value less than αα?
- Make a decision.
- Make a conclusion.
- There is sufficient evidence to warrant rejection of the claim that all 5 categories are equally likely to be selected.
