We have been given the data: 47,45,44,41,48

$Mean=\frac{\text{sum of observations}}{\text{number of observations}}$

On substituting the values in the above formula to find mean:

$Mean=\frac{47+45+44+41+48}{5}$

$Mean=\frac{225}{5}=45$

Now, we need to find the absolute deviation that is:

$\text{absolute deviation}=\sum{|x-\bar{x}|}$

Where $\bar{x}$ is the mean and x is the values given of x which are: 2,0,1,4

$\text{absolute deviation}=|2-45|+|0-45|+|1-45|+|4-45|=43+45+44+41$

$\Rightarrow \text{absolute deviation}=173$

Now, to find mean absolute deviation we have a formula:

$\text{mean absolute deviation}=\sum\frac{(x-\bar{x})}{N}$

$\text{mean absolute deviation}=\frac{|47-45|+|45-45|+|44-45|+|41-45|+|48-45|}{5}$

$\text{mean absolute deviation}=\frac{2+0+1+4+3}{5}$

$\text{mean absolute deviation}=2$

The scale factor is $\frac{3}{2}$

Step-by-step explanation:

Yes the figures are similar to each other. The ratio of their linear measurements is in uniform ration

The ration of radius of large cylinder (R) to that of the smaller cylinder (r) is

$\frac{18}{12} \\\frac{3}{2}$

Like wise the ration of height of large cylinder (H) to that of the smaller cylinder (h) is

$\frac{30}{20} \\\frac{3}{2}$

The scale factor is $\frac{3}{2}$
