Answer:
The mean of Martin's scores is 85.2
Step-by-step explanation:
In order to find the mean of a set of numbers, you will have to add up all of the numbers and divide the result by the total numbers in the set.
98 + 78 + 84 + 75 + 91 = 426
Since there are 5 numbers in total, we will do 426 divided by 5.
426 ÷ 5 = 85.2
So, the mean of Martin's scores is 85.2
