Q3.4

3 Points

The chi-squared test statistic was computed as 23.156 and the p-value was 0.026. Because this p-value is less than our \alpha = 0.05

?=0.05, we will reject the null hypothesis.

Provide an interpretation of the p-value of 0.026 in context.

Q3.5

Now that we've interpreted the p-value, let's focus on the chi-squared test statistic of 23.156. What is the contribution to the test statistic from diamonds with color D and clarity C1?

0.0064

0.0048

5.6619

0.3162

If there is no association between color and clarity, what is the expected chi-square test statistic value?
