Explanation / Answer

Five number summary are,

minimum value, 1st quartile(Q1), median(Q2), 3rd quartile(Q3) and maximum value.

we have given

Min=445

1st quartile Q1=1334

Median(Q2)=1667

3rd quartile(Q3)=2106

max=6662

a) Range = max - min= 6662 - 445 =6217

therefore,

Range= 6217

And

IQR = Q3 - Q1 = 2106 - 1334 = 772

IQR= 772.

Where IQR stands for Inter Quartile Range.
