The step-by-step solution on how to solve questions 3,4,5 of week 4 practice quiz.
#5: The formula for SSAB=sum of squares for AB interaction (Housing and Weight class)=(sum of squares of the cell totals AB11, AB12... divided by the number of measurements in a single total, namely r) - SSA - SSB - CM.
CM=(Total of all n measurements)^2/n. In this formula, n is 28. For the numerator, you need to total all the measurements and then squ
