Question

Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower

class limits, and the upper class limits.
minimum = 10, maximum = 68, 7 classes

The class width is ?

The lower class limits are ?

The upper class limits are ?

Answer 1

1. To find the class width, we first need to find the range of the data, which is the difference between the maximum and minimum values: 68 - 10 = 58. Then, we divide the range by the number of classes to get the class width: 58 / 7 = 8.29. However, we will round up to the nearest whole number, so the class width is 9.

2. The lower class limits are 10, 19, 28, 37, 46, 55, and 64, since we add the class width to the lower limit of each previous class to find the lower limit of the next class.

3. The upper class limits are 18, 27, 36, 45, 54, 63, and 68, since we add the class width to the lower limit of each class to find the upper limit of that class.
