Our chi-squared statistic was six. So this right over here tells us the probability of getting a 6.25 or greater for our chi-squared value is 10%. If we go back to this chart, we just learned that this probability from 6.25 and up, when we have three degrees of freedom, that this right over here is 10%. boost energy top up as guestWebThe 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. has the view been canceledWebFind the critical chi-square value.
