Answer:
Mean: 80
Mode: 81
Median:81
Step-by-step explanation:
First, let's get the set of numbers from this Stem-and-Leaf plot:
[60,61,73,75,79,81,81,81,92,96,98]. From here we can solve for the mean by adding all the numbers up and dividing it by the number of terms that we have: [tex]\frac{60+61+73+75+79+81+81+81+92+96+98}{11} = 80[/tex] when rounded to the nearest whole number. The median is the middle number of the set when arranged from least to greatest, in this case, the median is 81.
Hope this helps! :)
