To find the median, we first need to arrange the data in order from least to greatest: 1.43, 2.31, 2.40, 2.75, 3.65. Since there are an odd number of data points, the median is the middle number, which is 2.40. To find the mean, we add up all the numbers and divide by the total number of data points.

(mean) = (1.43 + 2.31 + 2.40 + 2.75 + 3.65) / 5 = 12.54 / 5 = 2.51

Therefore, the best choice is B, which correctly identifies the median as 2.40 and the mean as 2.51.
