The correct formula is: dfs(#rows-1 )"(#columns-1) Trap with Peanut Trap with Total 83 120 154 237 QUESTION 9 2 points If the calculated chi-squared value is less than the critical value what can you conclude? O fail to reject the null model accept the alternative model O reject the null modell QUESTION 10 2 points Save Answer The closer the observed value is to the expected value, the more it contributes to the overall sum of the Chi-squared. O False QUESTION 11 1 points Save Answer

Explanation / Answer

Question 9-Answer

If calculated chi-square value is less than the chi-square critical value, then you "fail to reject" the null hypothesis

Answer-10

If the observed value is closure to the expected value, the more likely it is that the difference has arisen by chance.

FALSE

If observed and expected values are closer than the chi-square value is also low. A very small chi-square test statistic means that your observed data fits your expected data extremely well.
