Explanation / Answer

There are 7 elemts in data set

The data is given is acending order

So, 4th element is the median (middle term)

First quartile is the middle term of the elements before median

So, in the first 3, middle term is the second term.

So, the first quartile = 29

Median = 33

Mean = (27+29+30+33+39+42+47)/7

= 35.29

Mean is greater than the median

Claimed defective rate = (2/1000)x100 = 0.2%
