Use the frequency distribution to complete parts (a) Class through (e). Frequency 11 - 19 a) Determine the total number of observations. 20 - 28 b) Determine the width of each class. 29 - 37 -TWONUT c) Determine the midpoint of the second class. 38 - 46 d) Determine the modal class (or classes). 47 -55 e) Determine the class limits of the next class if an additional class were to be added. 56 -64 a) The total number of observations is b) The width of each class is c) The midpoint of the second class is (Type an integer or a decimal.) d) The modal class(es) is/are (Use a hyphen to separate the limits of a class. Use a comma to separate answers. Type the classes in order from smallest to largest.) e) The class limits of the next class if an additional class were to be added are (Use a hyphen to separate the limits of a class.)
