In a chi-square goodness-of-fit test,by combining cells we guard against having an inflated test statistic that could have caused us to: A)incorrectly reject the H₀. B)incorrectly accept the H₀. C)incorrectly reject the H₁. D)incorrectly accept the H₁.

Question

Combining cells can increase the expected cell frequency for each cell, ensuring that the test statistic is not inflated. If the test statistic is inflated, it could lead to the rejection of the null hypothesis (H₀) when it is actually true, leading to a type I error. Therefore, combining cells guards against this error, making choice A the correct answer.
