Question

find the mean of data an emprical formula mode=50.5 median=45.5

Answer 1

3median = mode + 2mean
by this empherical formula, mean is 43

Answer 2

Answer:

Mean (x) = 43

Step-by-step explanation:

Given ,

mode (z)= 50.5,

media (M) = 45.5,

Let mean = x,

We know the ,

Empharical formula :

mode = 3median - 2 mean

=> 50.5 = 3×45.5 - 2x

=> 2x = 136.5-50.5

=> 2x = 86

Divide each term by 2, we get

=> x = 43

Therefore,

Mean (x) = 43
