- A research analyst was directed to arrange raw data collected on the yield of wheat, ranging from 40 to 93 bushels per acre, in a frequency distribution. He should choose 30 as the class interval width.（
- True or False: When constructing a frequency distribution, classes should be selected so that they are of equal width.
- True or False: The larger the number of observations in a numerical data set, the larger the number of class intervals needed for a grouped frequency distribution.
- True or False: Determining the class boundaries of a frequency distribution is highly subjective.
- True or False: The original data values cannot be determined once they are grouped into a frequency distribution table.
