For this problem, use five classes.

(a) Find the class width.

(b) Make a frequency table showing class limits, class boundaries, midpoints, frequencies, relative frequencies, and cumulative frequencies. (Give relative frequencies to 2 decimal places.)

Step 1

(a)

The class width is ** 25** and it is calculated below:

**Class width formula:**

Step 2

From the given information, the maximum value is 360, the minimum value is 236 and the number of classes is 5.

Step 3

(b)

**Class Boundaries:**...
