Identify the class boundaries, the class marks, and the class interval. A cumulative frequency distribution is constructed from a frequency distribution by replacing each frequency with the sum of the frequency of the given class and the frequencies of all classes above it, and representing each ...Use MINITAB or some other computer software to construct a histogram of the drying- time data in Exercise 3.115.
