Calculation:

Range:

Range is the phrase used to describe the difference between the maximum and minimum values.

Range $=max-min$

Here, 120 is the lowest value and 180 is the highest.

Range $=max-min$

$=180-120=\mathrm{\$}60$

Therefore, the range is $\mathrm{\$}60$.

Inter quartile range:

The inter quartile range (also known as mid spread) is the difference between the third and the first quartile, as opposed to the range, which only accounts for differences between extremes. Thus, it measures the variation in the middle 50 percent ofjthe data and unlike the range it is not affected by extreme values. $IQR={Q}_{3}-{Q}_{1}$.

Substitute ${Q}_{1},\text{}as\text{}125\text{}and\text{}{Q}_{3}$ as 155 in the above formula,

$IQR=155\u2014125=\mathrm{\$}30$

Hence, the IQR for the cost of compact refrigerators is $\mathrm{\$}30$.

For the 1s orbital of the Hydrogen atom, the radial wave function is given as: $R(r)=\frac{1}{\sqrt{\pi}}(\frac{1}{{a}_{O}}{)}^{\frac{3}{2}}{e}^{\frac{-r}{{a}_{O}}}$ (Where ${a}_{O}=0.529$ ∘A)
