Question

If the coefficient of range is 0.4 and the lowest observation is 15. What will be the highest observation?​

Answer 1

Answer:

Let largest value of data be L

and smallest value of data be S.

We are given that the range and coefficient of range of the data are 20 and 0.2 respectively.

Range formula is given by = Largest value - Smallest value

20 = L - S

L = 20 + S ---------- [Equation 1]

Coefficient of range formula = (Largest - Smallest) ÷ (Largest + Smallest)

0.2 = l-s/l+s

0.2 = 20/l+s

L + S = 20/0.2 = 100

So, L + S = 100

20 + S + S = 100 {using equation 1}

2*S = 80

S = 80/2 = 40

Putting value of S in equation 1, we get L = 20 + 40 = 60

Therefore, Largest value, L = 60

smallest value, S = 40
