Beach

Cruise

US

209

280

Canada

225

248

Use a chi-square test to test the hypothesis (Ha) that nationality and type of vacation is not independent. Please show all six steps.

Solutions

Expert Solution

Solve using Excel:

Level of significance = 0.05

Degrees of freedom: df = (Roqs-1)*(Columns-1) = (2-1)*(2-1) = 1

H0: Nationality and type of vacation is independent

Ha: Nationality and type of vacation is not independent

Test statistic = 2.26

Critical value (Using Excel function CHISQ.INV.RT(probability, df)) = CHISQ.INV.RT(0.05,1) = 3.84

Since test statistic is less than critical value, we do not reject the null hypothesis.

So, nationality and type of vacation is independent.
