a. What are the median and range of his scores?
b. What is his mean (average) score so far?
c. 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?

Answer 1

If you help me with my last question I will help you with this one

Answer 2

Median= 9

Range= 2

Mean= 9.2

Mean after zero= 8.3

Explanation:

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

Median= order from least to greatest then eliminate from left to right until you get to the middle

Range= Subtract biggest # minus smallest #

Mean= add up all the numbers then divide by 9

Mean after zero= add 0 with other numbers then divide by 10
