Is mean affected by outlier
2 answers:
Answer with explanation:
Mean of a data set is defined as sum of all the observation divided by total number of observation.
For, example
Consider the Data set,the cost of five pens,={3,5,8,10,14}
Mean
Now, Two pens having cost $ 47 and $ 53 is included in the Data set
New data set of Seven pens,={3,5,8,10,14,47,53}
Mean
So, you can see there is variation or Difference between two means.
We can conclude from above two results ,that mean is affected by outlier.

Answer:
Correct answer is:
<em>a. (-9,17)</em>
Step-by-step explanation:
We are given that a point (6, 6) lies on the graph of .
Putting the values from the given point:
That means we are given that ..... (1)
And we have to find the corresponding coordinates of this point on the graph of
From equation (1), we know the value of .
so, let us convert to a form such that it becomes equal to
So, let us put in the given function:
Now, using equation <em>(1)</em>, putting
Therefore, the point the corresponding point is:
<em>a. (-9,17)</em>
