A Randomization Distribution Resulting from the Simulation of a Chi-Square

question 7

Multiple Choice

A randomization distribution resulting from the simulation of a chi-square test had 4% of the values at or above the chi-square statistic observed for the real sample.What decision would you make for the test, using a level of 0.05?

• A)Do not reject the null hypothesis.There is not enough evidence to conclude that the observed chi-square value is unusual.
• B)Reject the null hypothesis.There is sufficient evidence to conclude that the chi-square value is unusual.
• C)Since 4% = 0.04 < 0.05, the simulation needs to include more trails.
• D)There is not enough information to render a decision about the test.
