The best approach for replacing missing quiz scores with zeroes while coloring the background of those cells yellow is to: 1) Highlight the cells with missing values, color the cell backgrounds yellow, and enter zeroes in cells with missing values 2) Highlight adjacent cells with missing values, color the cell backgrounds yellow, and then change the missing values to zeroes 3) Use the Go To Special function on the quiz and exam scores to color the cell backgrounds and enter zeroes in cells with missing values 4) Use the Go To Special function on the quiz score range to color the cells with missing values and set them to zeroes
