Determine whether the statement is true or false. If it is false, rewrite it as a true statement. The midpoint of a class is the sum of its lower and upper limits divided by two. Choose the correct answer below. OA. The statement is false. A true statement is "The midpoint of a class is the class frequency divided by the sample size." B. The statement is false. A true statement is "The midpoint of a class is the average of its lower and upper limits." OC. The statement is false. A true statement is "The midpoint of a class is the difference of its lower and upper limits divided by two." O D. The statement is true.
