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 ... WebSolution: Now calculate Chi Square using the following formula: χ 2 = ∑ (O − E) 2 / E Calculate this formula for each cell, one at a time. For example, cell #1 (Male/Full Stop): Observed number is: 6 Expected number is: 6.24 Therefore, (6 – 6.24) 2 /6.24 = 0.0092
