Answer
The following figure shows the the grouped frequency distribution with 6 classes,
the frequency histogram, the frequency polygon, and an ogive.
From the distribution, we can see that it is right skewed and the cumulative
frequency becomes flat towards higher numbers.
Work Step by Step
Data range: $254-3=251$
Bin width (6 classes): $\frac{251}{6}=41.8\approx42$
Start point: 2.5 (to avoid any data fall on the boundaries)
Count the number of data point in each bin for the frequency as listed in the figure above.
