We are given a histogram of frequencies of the weight of grown pumpkins. This means that we have in the horizontal axis the weight of pumpkins and on the veritical axis the frequency or the number of times that the number is repeated.
The second bin represents the number of pumpkins that weighed 48 lb.
To determine the weight of 16 pumpkins, we draw a horizontal line on the number that corresponds to the frequency of 16 until the line touches the top of the bin. Now we draw a vertical line on the right side of the bin until we reach the horizontal axis. There we should be able to read the weight. As follows:
Therefore, 16 pumpkins weighed 4.8 lb.
