Forty plasma TVs were tested, and the number of watts per hour they used recorded. Given that the values ranged from a low of 435 to a high of 503, calculate the width to be used in the construction of a frequency distribution for the data with 6 classes. To find the width, find the difference between the highest and lowest data values, divide by the number of classes, and round up to the next odd number.
