Final answer:
To make a histogram of the books Harry read by page length, we need to determine the frequency of each page length. Then, we can create a bar graph with the page length on the x-axis and the frequency on the y-axis. The page length that Harry read the most can be determined by finding the highest frequency on the y-axis of the histogram.
Step-by-step explanation:
To make a histogram of the books Harry read by page length, we need to determine the frequency of each page length. Then, we can create a bar graph with the page length on the x-axis and the frequency on the y-axis.
The page lengths given are: 452, 409, 355, 378, 390, 367, 375, 514, 389, 438, 311, 411, 376.
The page length that Harry read the most can be determined by finding the highest frequency on the y-axis of the histogram.
