The 65th percentile is 37

Step-by-step explanation:

The 65th percentile is the number that splits the data in two groups. The amount of data that is less to the 65th percentile corresponds to the 65% of the data. Since we have 20 value, we calculate the 65% of 20, which is 13. By organazing the data from least to greatest, we count the values in the data set until we reach the 13th value, which in this case is 37.
