A homeowner was reading through a summary of his electric usage for the previous year. Typical high temperatures for each month were included in the summary and the teacher became curious about the distribution of those temperatures. Here are the data (measured in degrees Fahrenheit).

Which of the following is the correct calculation and interpretation of a percentile?
A. The month in which the typical high temperature was 48 degrees is at about the 25th percentile. This means that this month's typical high temperature was less than about 25% of all months.
B. The month in which the typical high temperature was 79 degrees is at about the 16th percentile. This means that about 16% of the time the high temperature will be about 79 degrees.
C. The month in which the typical high temperature was 31 degrees is about at the 8th percentile. This means that about 8% of the time, the typical high temperature will be similar for this month in the future.
D. The month in which the typical high temperature was 71 degrees is at about the 58th percentile. This means that this month's typical high temperature was greater than about 58% of the other months.
