Question

From the given information in each case below, state what you know about the P-value for a chi-square test and give the conclusion for a significance level of α = 0.01. (Enter your answers to three decimal places.)

a)  χ² = 7.42, df = 2   _____ < P-value < ______

b)  χ² = 13.04, df = 6 _____ < P-value < ______

c)  χ² = 17.89, df = 9   _____ < P-value < ______

d)  χ² = 20.22, df = 4 P-value < _____

e) χ² = 5.65, df = 3 P-value > _____

Answer 1

We can find the P-value using the excel formula

CHISQ.DIST.RT(chi square value , df)

We will reject the null if P value
