Answer:
37 cups
Explanation:
From the plot given for the volume of water collected for the 14 creek water samples ;
The largest volume of water collected is 9 1/4, with a frequency of 4 ; hence the 4 largest water samples collected are each 9 1/4 cup.
Hence, the total volume of water in the 4 largest samples equals :
(9 1/4 + 91/4 + 9 1/4 + 9 1/4)
(36 + (1/4 + 1/4 + 1/4 + 1/4)
(36 + (4/4))
(36 + 1)
= 37 cups
