The following is the output of the test for the null hypothesis: sigma squared_b

Question

The following is the output of the test for the null hypothesis: sigma squared_burgerking = sigma squared_checkers, where the sigma squared is the variance of monthly sales (in thousands). Given the output, what can you conclude? Use alpha = .05. The variance of monthly sales for Burger King and Checkers are not significantly different The variance of monthly sales for Burger King and Checkers are significantly different The variance of monthly sales for Burger King is significantly higher than that for Checkers The variance of monthly sales for Burger King is significantly lower than that for Checkers If you conduct a Chi-square test to test for the independence between two categorical variables, and you get a p-value of .03, what can you conclude? Use alpha = .05 These two variables are independent These two variables are dependent

Explanation / Answer

Q 8 Since Alternate hypothsi is nottgiven that it is lft tailed or right tailed, and F calculated is greater than F critical we reject H0 and conclude that the variance of monthly sales for Burger king and checkers are significantly different.

Option B

Q9. since p value is less than level of significance, we reject null hypothesis and colcude that these two varaiable are dependent.

Option B.
