Question 1Last 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. Teachers 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 areasH1: There is a significant difference in the sales per run between the delivery areasNotice 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 own sales for each area in a column and click the Megastat menu, select analysis of variance, and highlight your data and click enter. Check your p-value. Interpret.Here is the teachers example :      Area 1    Area 2     Area 3   Area 4    Area 5 $  45.00  $  13.00  $  12.00  $  34.00  $  37.00 $  34.00  $  24.00  $  37.00  $  25.00  $  22.00 $  36.00  $  34.00  $  27.00  $  23.00  $  32.00 $  45.00  $  23.00  $  17.00  $  36.00  $  42.00 $  53.00  $  32.00  $  28.00  $  23.00  $  35.00 $   43.00  $  21.00  $  39.00  $  35.00  $  37.00 $  45.00  $  23.00  $  35.00  $  45.00  $  28.00 $  65.00  $  24.00  $  26.00  $  34.00  $  13.00 $  32.00  $  37.00  $  45.00  $  23.00  $  24.00 $  30.00  $  45.00  $  27.00  $  53.00  $  15.00 $  40.00  $  32.00  $  34.00  $  29.00  $  63.00 $  23.00  $  34.00  $  16.00  $  28.00  $  35.00             One factor ANOVA                          Mean  n  Std.
