Answer 1

Answer:

sorry I don't know..............

Answer 2

Answer:

Concept:

The following formulas are used-

Q1 = N+1/4

D4 =(N + 1)*4/10

P26= 26*(N+1)/100

Given:

Data-

4,7,8,9,10,12,16,18,24,25,26,28,29,45,49

To find:

The value of Q1, D4 and P26

Solution:

The number of observations here is 15

By using the formulas,

Q1= 15+1/4 th term

=4th term

= 9

Therefore, Q1 is 9.

D4= (15+1)*4/10th term

=6.4th term

=12 + 4/10*4

=13.6

Therefore, D4 is 13.6.

P26= 26* 16/100

= 4.16th term

=9.16

Therefore, P26 is 9.16
