Answer:
Option a) Mean
Mean is affected a lot by the change in the last observation as the median remains the same.
Step-by-step explanation:
we are given the following in the question:
Data set A: 64, 65, 66, 68, 70, 71, 72
Data set B: 64, 65, 66, 68, 70, 71, 720
For data set A, the mean and median are 68.
For data set B:
Formula:

Sorted data:
64, 65, 66, 68, 70, 71, 720

Clearly, 720 is the is a outlier.
As seen mean is affected a lot by the change in the last observation as the median remains the same.
It's a cubic with a positive x^3 coefficient. The general shape is "/".
It goes to -∞ for large negative x.
It goes to +∞ for large positive x.
The answer is definitely 60%
Answer:
If you center the series at x=1

Where
is the error.
Step-by-step explanation:
From the information given we know that

(This comes from the chain rule )
(This comes from the chain rule and the product rule)
(This comes from the chain rule and the product rule)
If you center the series at x=1 then

Where
is the error.
Slope of perpendicular is -1/3.
Then equation is
y-5=(-1/3)(x+9)
