Answer
The following figure shows the
histogram, frequency polygon, and ogive for the data, using relative frequencies.
The shape of the histogram is non-symmetric and right skewed.
Work Step by Step
Data Range: 270-80=190
Total data points: 46
Bin width (7 classes): $190/7=27.1$ use 28
Start point (bin1): 79.5 to avoid any data fall on the boundaries
Count the frequency in each bin
Calculate relative frequency
Calculate cumulative frequency.
