Answer:
a. 8.5
b. 10
Step-by-step explanation:
a.) 1, 1, 2, 7, 7, 10, 12, 16, 20, 34
Since 7 and 10 are tied in the middle, then we need to find a number in the middle of the two.
8.5 is in the middle of 7 and 10, therefore 8.5 is the mean.
b.) We need to do the same thing we did before, except add 22 to it's directed place:
1, 1, 2, 7, 7, 10, 12, 16, 20, 22, 34
Since 10 is in the middle, 10 is the new mean.
Hope this helps! :D
