Chi-square values are always
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 ...

So, when you get a p-value of 0.000, you should compare it to the significance level. Common significance levels include 0.1, 0.05, and 0.01. Since 0.000 is lower than all of these significance levels, we would reject the null hypothesis in each case. fnaf security breach wa
