Question 9.
11, 17, 7, 6, 7, 4, 15, 9 _________
Put number in order centering 4, 6, 7, 7, 9, 11, 15, 17
Median is the middle number; found by ordering alt data points and picking out the one in the middle. There are three middle numbers, so take the mean of those three numbers).
centering Median = $$\frac{6+7+11}{3}$$ = $$\frac{24}{3}$$ = 8

Mode = 7
centering Median= 8
centering Mode= 7

Question 10.
43, 37, 49, 51, 56, 40, 44, 50, 36 _____
