Use the tally() function to produce the correct answer for each of the questions listed below.
Carefully choose the correct field operators and logical operators when writing the tally() function.
In your final Word document, circle the correct answer for each question when the results of the tally() function create a table rather than a single answer. Failure to circle the correct answer will result in zero points for that question.
