Explanation / Answer

here minimum =445

Q1=1334

median=1667

Q3 =2106

maximum=6662

hence range =max-min=6217

IQR =Q3-Q1 =2106-1334=772

b)as above distribution seems to be right skewed hence mean should be higher then median

therefore mean =1796

c)approximate value of std deviation =Range/4 ~1897
