The correct answer is (a) 31.
The mode is the value that occurs most frequently in a data set. The median is the middle value in a data set when the data is arranged in order from least to greatest. The arithmetic mean is the sum of the values in a data set divided by the number of values in the data set.
In this case, the mode is 28 and the median is 31. This means that the value 28 occurs more frequently than any other value in the data set, and that half of the values in the data set are less than or equal to 31, and half of the values in the data set are greater than or equal to 31.
The arithmetic mean is likely to be
