Using the contingency table for the problems.
A) The total sale amounts for each entire marking period (start, end) is a population
B) µ= Mar Per (Start/End) Sales Total
3
C) a= 0.05
1. Do a two-way-ANOVA. Tell us how the results apply to sales predictions.
Ho: No interaction between time-of-the-school and study-guide-type
H1: There is interaction between time-of-school-year and study-guide-type.
If Ho is supported then
Ho: Time-of-the-year does not affect sales.
H1: Time-the-school-year does affect sales
And
Ho: Study-guide-type- does not affect sales.
H1: Study-guide type does affect sales
