Answer 1

6)

mean of all prime numbers

between 1 to 100

prime numbers are 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97.

mean=sum of observations/no.of observations.

sum of prime numbers is 1060.

mean=1060/25.

mean =42.4.

7) The first 15 odd numbers are 1, 3, 5, 7, 9, 1, 13, 15, 17, 19, 21, 23, 25, 27 and 29

Here n = 15, which is odd.

Where, n is the number of the given number.

∴median = value of 1 / 2(\mathrm{n}+1)^{\mathrm{th}} observation.

= ½ (15 + 1)

= ½ (16)

= 16/2

= 8

Then, value of 8th term = 15

Hence, the median of first 15 odd numbers is 15.

Answer 2

Answer:

mean of all prime number 1 to100

2 ,3 ,5 ,7 ,11 ,13,17,19,23,29,31,37,41,43,47,53,59,61,67, 71,73,79,83,89,97

mean = sun of observations/ no.of observations

sum of prime number 1060

1060/25 = 42.4.

mean = 42.4

the first 15 odd number are

1,3,5,9,11,13,15,17, 19, 21,23,25,27,29

median = value of 1/2 (n+1)

1/2 (15+1)

1/2 (16)

16/2 = 8

then value of 8th term 15.

8) 1/3
