For the sample Data given create a frequency table using 6
classes.
Find all relative and cumulative frequencies
Data:94.7, 106.1, 117.5, 128.9, 135.5, 139.2, 142.3, 143.1,
144.5, 152.5, 156.4, 158.5, 159.6, 165.7, 166.5, 173.2, 175.5,
188.0, 199.0, 216.1
Use the frequencies found in the table above to sketch the
histogram for the distribution. Use the class boundaries for the
horizontal axis.
