It might be predicted that consumer buying behavior would varywith the location of products in a store. Therefore, a team ofmarket researchers looked at the sales per day for a well-known andunknown brand of candy bars. Additionally, the researchers placedthe candy bars in the usual location and next to the cash registerin different stores. What can the market researchers conclude withan ? of 0.05?

known brand/ usual	known brand/ cash register	unknown brand/ usual	unknown brand/ cash register
16 24 19 17 26 30 18	25 15 16 20 31 27 19	11 6 9 13 14 7 11	19 18 16 21 22 17 19

a) Compute the appropriate test statistic(s) tomake a decision about H₀.
Location: critical value =  ; teststatistic =  


Brand: critical value =  ; teststatistic =  
Decision:  ---Select--- Reject H0 Fail to reject H0

Interaction: critical value =  ; teststatistic =  
Decision:  ---Select--- Reject H0 Fail to reject H0


b) Compute the corresponding effect size(s) andindicate magnitude(s).
Location: ?²=  ;  ---Select--- na trivial effect smalleffect medium effect large effect
Brand: ?²=  ;  ---Select--- na trivial effect smalleffect medium effect large effect
Interaction: ?²=  ;  ---Select--- na trivial effect smalleffect medium effect large effect


c) Make an interpretation based on theresults.

There is a location difference on candy bar sales.There is nolocation difference on candy barsales.     

There is a brand difference on candy bar sales.There is no branddifference on candy bar sales.     

There is a location by brand interaction on candy barsales.There is no location by brand interaction on candy barsales.
