Chapter problem 11.41 To conduct an ANOVA test to determine if there is a difference in the average number of hours per week of television viewing by the four age groups, what is the correct hypothesis of the test? Not all are equal None of above QUESTION 2 Chapter problem 11.41 If we want to conduct an ANOVA test to determine if there is a difference in the average number of hours per week of television viewing by the four age groups, what is the number of populations being compared (k)? O 20 QUESTION 3 Chapter problem 11.41 Perform a one-way ANOVA using a = 0.05 to determine if there is a difference in the average number of hours per week of television viewing by the four age groups, the grand mean for these observations is 21 33.75 34 O 35

Explanation / Answer

Question 1:

For testing whether there is a difference between the means across 4 groups, the null and the alternate hypothesis are given as:

Null Hypothesis: All means are equal

Alternate Hypothesis: All means are not equal.

Therefore b is the correct answer here.

Question 2:

Clearly as we are comparing 4 populations here. Therefore k = 4 would be degrees of freedom here.

Therefore k = 4 is the required answer here.

Question 3:

The chapter problem 11.41 is not given ( so this cannot be solved from the given information )
