Answer 1

Answere:

• The remaining two observation are 6 and 8

__________________

Given that:

• The mean of 6 observation is 15.
• Four of the observation are 10 ,18, 23 Eand 9.
• The remaining two observation one is four times the other.

__________________

To find:

• what are the remaining two observation?

__________________

Let us assume:

• Let the one of the observation be x.
• Other observation = 4x

__________________

Formula used:

• Mean = ( Sum of observations)/(Number of observations)

__________________

Finding the remaining two observations:

• According to the question

=> 15 = (10+18+23+9+x+4x)/6

• Cross multiplication

=> 10+18+23+9+x+4x = 15×6

=> 60+5x = 90

=>5x = 90-60

=> 5x = 30

=> x = 6

Remaining observation are:

• One observation = x = 6
• Other observations = 4x = (4×6) = 24
