I need support with this Business question so I can learn better.
Question 1
Last week we discussed the one sample hypothesis test. This week we will discuss ANOVA. The ANOVA allows us to test the mean between two or more groups.
For example, I have five pizza delivery areas and I want to know if the average sales per run is different in one area than any of the other areas.
H0: There is no significant difference in the sales per run between the delivery areas
H1: There is a significant difference in the sales per run between the delivery areas
Notice how the hypothesis is very simple. There is a difference or there is not a difference. Again, we will use MegaStat. You cannot calculate ANOVA by hand.
Just put your sales for each area in a column and click the Megastat menu, select analysis of variance, and highlight your data and click enter. Check you p-value. Interpret.
Here is my example and I look forward to yours:

The p-value is less than .05 so I do not reject the null
