Executive Training School offers typing classes. Each final exam evaluates a student’s typing speed and the number of typing errors made. Develop the logic for a program that produces a summary table of each examination’s results. Each row represents the number of students whose typing speed falls within the following ranges of words per minute: 0–19, 20–39, 40–69, and 70 or more. Each column represents the number of students who made different numbers of typing errors—0 through 6 or more.
