Question

Please solve only question 2 .it is very important.

Answer 1

Given data is 31,37,29,41,35,35,38,36,35,38,32,29,43.

(a)

Range = Highest value - Lowest value

⇒ 43 - 29

⇒ 14.

(b)

Arrange the data in ascending order.

29,29,31,32,35,35,35,36,37,38,38,41,43.

Number of observations n = 13.

Median = [(n + 1)/2]^th observation

             = (13 + 1)/2

             = 14/2

             = 7.

Therefore, Median = 35.

(c)

Mean = Sum of observations/Number of observations

          = 459/13

          = 35.3.

Therefore, mean = 35.3.

(d)

Mode = Which number shows up the most.

Here, 35 occurs maximum number of times.

So, Mode = 35.

Hope it helps!
