b. The bottom 60% of families have about 32% of the income, and the bottom 40% of families have about 16% of the income. So the third quintile has about 32% − 16% = 16%.
For the first questions it is x = -2 then the second one is x = 12 the third is x = 15

Answer:
The mean and SD will change
The median is a better measure of the center since it will not change in this case
Step-by-step explanation:
Given that the value 100 was changed to 15, what will happen is that the value of the mean will decrease since there is a lower total value now. This will consequently decrease the value of the standard deviation too.
Yes, the median will be a better choice
This is because, by changing the value of 100 to 15, the value of the median stays the same and thus the previous information would not be changed if the median we used .
