Explanation:

Step1: Calculate the mean

The mean is the sum of the numbers divided by the count of numbers. The numbers are 73, 84, 101, 81, 91. The sum is \(73 + 84 + 101 + 81 + 91 = 430\). There are 5 numbers, so the mean is \(\frac{430}{5}=86\).

Step2: Calculate the median

First, order the numbers: 73, 81, 84, 91, 101. The median is the middle number. Since there are 5 numbers (odd count), the middle one is the 3rd number, which is 84.

Step3: Calculate the mode

The mode is the number that appears most frequently. In this set, each number appears only once, so there is no mode (DNE).

Answer:

mean: 86
median: 84
mode: DNE
