Problem 1:
We have introduced a new feature on our new webpage. To test the effectiveness of the new feature, we have conducted an A/B test and displayed the new and old webpage to 1,000 potential customers separately. We would like to know if our new feature is significantly better
than the old feature.
The result of our analysis is presented in the SAS04_AB_testing.sas program. To analyze the results, perform the following:
1. Download the "SAS04_AB_testing.sas" into your SAS_PGM folder.
2. Log into Apporto and then SAS
3. Open the "SAS04_AB_testing" program in the SAS editor
4. Run lines 10 to 24 and interpret the results; is the new feature better than the old feature?
5. Would your answer change if only 325 customers clicked on the webpage?
Problem 2:
What would you do If you wanted to conduct a test that could detect a 2% difference from a 30% click rate. Assume beta=20 and alpha=.05
Problem 3:
We would like to know whether the location of a store makes a difference in sales. We have tracked the sales for four stores in different locations for the past four weeks. Analyze the results by performing the following:
1. Download the Mod04_Sales SAS dataset from CANVAS into your SAS_Data folder.
2. Download the Mod04_anova_testing, from CANVAS into your SAS_PGM folder
3. Use proc copy to copy the Mod04_sales data into the SAS work environment
4. Run proc ANOVA and interpret the results.
