Answer 1

Answer:

a)mean=sum of observations/no of observations

=1+3+5+7+9+11+13+15+17+19/10

=100/10=10

median =9+11/2 =20/2=10

b) mean=4+8+12+16+20+24+28/7=112/7=16

median =16

hope it helps you and don't forget to follow me

Answer 2

(a). First ten odd numbers = 1,3,5,7,9,11,13,15,17 and 19

median = (n¹ + n²/2) (even)

=> (9+11/2)

=> 20/2

=> 10 answer

Therefore, median of first 10 odd numbers = [ 10]

(b). seven multiples of 4 are:

4, 8,12,16,20,24,28

mean = 4+8+12+16+20+24+28/7

=> 112/7

=> 16

Median = (n+1/2)th term

n = 7

= (7+1/2)th term

= (8/2)th term

= 4th term

mean is 16

median is 4th term = 16
