QUESTION-

Emma's On-the-Go, a large convenience store that makes a good deal of money from magazine sales, has three possible locations in the store for its magazine rack: in the front of the store (to attract "impulse buying" by all customers), on the left-hand side of the store (to attract teenagers who are on that side of the store looking at the candy and soda), and in the back of the store (to attract the adults searching through the alcohol cases).

The manager at Emma's experiments over the course of several months by rotating the magazine rack among the three locations, choosing a sample of 46 days at each location. Each day, the manager records the amount of money brought in from the sale of magazines.

Below are the sample mean daily sales (in dollars) for each of the locations, as well as the sample variances:

Suppose that we were to perform a one-way, independent-samples ANOVA test to decide if there is a significant difference in the mean daily sales among the three locations.

Answer the following, carrying your intermediate computations to at least three decimal places and rounding your responses to at least one decimal place.

(1) What is the value of the mean square for treatments (the "between groups" mean square) that would be reported in the ANOVA test? :_________________

(2) What is the value of the mean square for error (the "within groups" mean square) that would be reported in the ANOVA test?: ________________

I DID EXCEL ANOVA ONE WAY: Is this correct method?

SO WHAT IS ANSWER 1?____________

WHAT IS ANSWER 2?____________

Below are the sample mean daily sales (in dollars) for each of the locations, as well as the sample variances:

Suppose that we were to perform a one-way, independent-samples ANOVA test to decide if there is a significant difference in the mean daily sales among the three locations.

Answer the following, carrying your intermediate computations to at least three decimal places and rounding your responses to at least one decimal place.

Group Front Left-hand side Right-hand side Sample Sample Sample variance mean SIze 46 514.7 213.5 207.7 486.2 46 46 214.8 426.2

Explanation / Answer

No that method is applicable when u know the input; but they have given upper output of excel

here SSE =(514.7)*45+(486.2)*45+(426.2)*45=64219.5

for overall average =(213.5+207.7+214.8)/3=212

hence b/w groups SSA =(212-213.5)2*46+(212-207.7)2*46+(212-214.8)2*46 =1314.68

hence ANOVA table will look like this

1) mean square for treatments =657.34

2) mean square for error =475.7

Source of Variation SS df MS F P-value Between Groups 1314.68 2 657.34 1.381837 0.254645 Within Groups 64219.5 135 475.7 Total 65534.18 137
