Question

On Fulton Avenue. Burger King is just across the street from Checkers. If you want to know whether the average monthly sales of these two fast food stores are the same or not when the population standard deviations are unknown, what statistical test should you conduct? Two-sample z test Two-sample t test Paired t-test Chi-square test for one population variance Chi-square test for the equality of population proportions for > = 3 populations Chi-square test for the independence of two categorical variables. F test for two population variances. On Fulton Avenue, three fast food restaurants are dose to each other. Burger King. Checkers, and Popeyes. If you want to know whether the average monthly sales of these three fast food stores are the same or not. What statistical test should you conduct? Two-sample z test Two-sample t test Paired t-test Chi-square test for one population variance Chi-square test for the equality of population proportions for > = 3 populations Chi-square test for the independence of two categorical variables F test for two population variances F test for the equality of population means for > = 3 populations You want to know whether the variance of the monthly sales of Burger King is the same as that of Checkers To answer your question, what test should you do? Two-sample z test Two-sample t test Paired t-test Chi-square test for one population variance Chi-square test for the equality of population proportions for > = 3 populations Chi-square test for the independence of two categorical variables F test for two population variances F test for the equality of population means for > = 3 populations To understand consumers' preference between Burger King and Checkers, you have 30 consumers and asked them to write down their gender and the name of their preferred store (either Burger King or Checkers). You then created an observed frequency table to count the number of female/mate consumers who prefer Burger King/Checkers. What statistical test should you conduct if you want to know whether preference is independent of gender? Two-sample z test Two-sample t test Paired t-test Chi-square test for one population variance Chi-square test for the equality of population proportions for > = 3 populations Chi-square test for the independence of two categorical variables F test for two population variances F test for the equality of population means for > = 3 populations

Explanation / Answer

Q.1> We have to test equality of two means when the population standard deviation is unlnown. So we have to replace it with its' sample version. So Two-sample t-test will be appropriate here. So 2nd option is the correct choice.

Q.2> In this case we have to test equality oif more than 2 means. So F-test for the equality of population means for >=3 populations will be appropriate here. So last option is the correct choice.

Q.3> Here F-test for two population variances should be done. So the 7-th option is the correct choice.

Q.4> Here we have to perform chi-square test for the independence of two-categorical variables. So the 6-th option is the correct choice.
