Question

hello i cant figure this out and ill paste it: 10,10,9,9,10,8,9,10,8. Mark did not do the tenth assignment, so he got a zero on it. Zero is an outlier for these assignments. What is his new mean? I need help bad with it

Answer 1

Well since Mark did not do one assignment that means we have 10 numbers to deal with so let’s line them up.

0, 8, 8, 9, 9, 9, 10, 10, 10, 10

So to find the mean we have to add all of numbers together then divide that by the amount of assignments he had.

So we have
83/10 = 8.3


So 8.3 would be your mean

And an outlier is when you have a number far off from the number range you’re using.
