(08.06)The following data show the height, in inches, of 11 different garden gnomes:
Elodia [21]

Answer:

The correct statement is:

On average, the height of a garden gnome varies 3.2 inches from the mean of 6 inches.

Step-by-step explanation:

We are given a data of 11 gardens as:

2   9    1    23    3    7    10    2    10    9     7

Now on removing the outlier i.e. 23 (since it is the very large value as compared to other data points) the entries are as follows:

x         |x-x'|        

2          4              

9          3              

1           5              

3          3              

7           1                

10         4              

2           4              

10          4              

9           3              

7            1              

Now mean of the data is denoted by x' and is calculated as:

x'=\dfrac{2+9+1+3+7+10+2+10+9+7}{10}\\\\x'=\dfrac{60}{10}\\\\x'=6

Hence, Mean(x')=6

Now,

∑ |x-x'|=32

Now mean of the absolute deviation is:

\dfrac{32}{10}=3.2

This means that , On average, the height of a garden gnome varies 3.2 inches from the mean of 6 inches.

4x=7y+9

4x+y=17

7y+9+y=17

8y=17-9

8y=8

y=1

4x=7*1+9

4x=16

x=16/4

x=4
