Answer:
(0,-9)
Step-by-step explanation:
The image of a point
over a line
is given by the co-ordinate rule:
→ 
So, when we reflect a point over the line
, the x co-ordinate and y co-ordinate change their places.
Here,
is
. So, from the above rule, after reflection over the line
, the image has the following co-ordinates:

1. The mean is calculated using:
(9.4 + 17 + 7.3 + 7 + 16.1 + 5.4 + 5.9 + 8.5 + 4.2 + 9.2)/ 10
= 9
2. The standard deviation is 4.31
3. The years are 1996, 1997, 1999-200
