WebThe Chi-square value with α = 0.05 and three degrees of freedom is 7.815. We compare the value of our test statistic (65.03) to the Chi-square value. Since 65.03 > 7.815, we reject the idea that movie type and snack purchases are independent. We conclude that there is some relationship between movie type and snack purchases. The owner of the ...
