Find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given question.

(a) Find the mean.
(b) Find the median.

(a) Mean = 42.64

(b) Median= 37

(d)Midrange =39

Step-by-step explanation:

Given data,

60,31,19,55,21,37,94,62,41,15,34

(a)

Mean: Mean is the ratio of all observation to the total number of observation.

        =42.64

(b)

To find the mean of given data,first we have to arrange the date in ascending order or descending order.

Median: Median is middle term of the observation.

15,19,21,31,34,37,41,55,60,62,94

    n = Total number of observation=11

              = 6th term

              =37

(c)

Mode is a observation which repeat maximum time.

Here all observations have only one one frequency, so it is multimodel data.

(d)

Midrange: The substraction of first quartile from third quartile.

First quartile: The mid-value of lower half.

Lower portion :15,19,21,31,34

Third quartile: The middle value of upper half.

upper half: 41,55,60,62,94

Mid range =

                 =60-21

                 =39

use formula for the circle a=3.14
