Final answer:
The class width, lower class limits, and upper class limits can be found by determining the number of classes and using the given minimum and maximum values. The class width is determined by dividing the range by the number of classes, while the lower class limits can be found by adding the class width to the lower limit of the first interval and the upper class limits can be found by subtracting 0.1 from the lower class limit of each interval.
Step-by-step explanation:
The class width can be found by subtracting the lower class limit from the upper class limit and dividing by the number of classes. In this case, we have 5 intervals and the upper and lower class limits are given as 32.5 and 100.5 respectively. Therefore, the class width is (100.5 - 32.5) / 5 = 13.6.
To find the lower class limits, we start from the lower class limit of the first interval (32.5) and add the class width successively for each interval. The upper class limits can be found by subtracting 0.1 from the lower class limit of each interval to prevent values from falling on interval boundaries.
So, the lower class limits for the intervals are: 32.5, 46.1, 59.7, 73.3, 86.9. The upper class limits for the intervals are: 46.0, 59.6, 73.2, 86.8, 100.4.
