All other options stated above are incorrect except option C
Answer:
Class width = max value-min value/# of classes
Class width is the difference between two consecutive lower class limits (or two consecutive lower class boundaries) in a frequency distribution.
The lower (and upper) class limits are the smallest (and largest) numbers that can belong to the different classes.
The lower (and upper) class limits are the smallest (and largest) numbers that can belong to the different classes.
The first lower class limit is approximately 90, and the second lower class limit is approximately 120.
Determine the distance between them.
120−90=30
Therefore, the class width is 30.
The approximate lower class limit of the first class is the first approximate lower class limit found above (approximately 90). The upper class limit of the first class is approximately equal to the second lower class limit, 120.
Therefore, the approximate lower and upper class limits of the first class are 90 and 120, respectively.
