Question

Next you must compare the X2 value you calculated to the appropriate value in the Chi Square table below. Which p value column will you use?

1) 0.01
2) 0.05
3) 0.10
4) 0.20

Answer 1

The appropriate p-value column to use when comparing the calculated χ² value to the Chi Square table is typically the column that corresponds to the pre-determined significance level of the test, commonly 0.05.

Step-by-step explanation:

When comparing the calculated χ² value to a Chi Square table, the p-value column you use depends on the significance level (α, alpha) you have set for your test. Typically, the significance level is set before conducting the test and represents the threshold for determining if the results are statistically significant. The most common significance level used is 0.05. So, if your significance level (α) is set to 0.05, you would compare your calculated χ² value with the p-value column of 0.05 to determine if the result is statistically significant.

From the provided information, we can infer that the textbook assumes a significance level of 5 percent, α=0.05, for the critical value method. Therefore, according to the guidance from the textbook, the appropriate p-value column for comparison would be column 2, which corresponds to a significance level of 0.05 (2) 0.05.
