Question

7. True/false: A Chi Square distribution with 2 df has a larger mean than a Chi Square distribution with 12 df. (relevant section) 8. True/false: A Chi Square test is often used to determine if there is a significant relationship between two continuous variables. (relevant section) 9. True/false: Imagine that you want to determine if the spinner shown below is biased. You spin it 50 times and write down how many times the arrow lands in each section. You will reject the null hypothesis at the .05 level and determine that this spinner is biased if you calculate a Chi Square value of 7.82 or higher. (relevant section)

Explanation / Answer

7) E(x) = Mean = df

Hence false.

8) False (only for discrete variables)

9)
Spinner df = 4-1 =3

Yes true.
