Answer

a) Mean=

Total no. of observations

sum of the number

⇒ Mean=

40

2+3+4+3+5+5+6+7+8+9+6+6+5+3+13+7+8+8+2+9+11+7+8+4+5+45+48+60+42+53+47+51+54+49+48+47+53+48+44+46

⇒ Mean=

40

119+770

,

40

889

=22.2

∴ Mean=22.2

b) To arrange data in ascending order

Median : 2,2,3,3,3,4,4,5,5,5,5,6,6,6,7,7,7,8,8,8,8,9,9,11,13,42,44,45,46,47,48,48,49,51,53,53,54,60.

Median =

2

8+8

=

12

6

=8

c)

Mode :- The only number which appears multiple times

Mode =2,3,4,5,6,7,8,9,48,53

Answer 2

Answer:

mean = 7

mode = 5

median = 1,3,3,3,5,5,5,5,7,7,7

so the median is ib mid point

median is 5

now how to find range.....

2+9+3+6+12+8 / 6

= 6 is the range....
