Question

Given the following data for X and Y variables,calculate Ó(X +Y) 
A)49 
B)9 
C)14 
D)29

Quizplus · Accepted Answer

Ó(X+Y) = ÓX + ÓY
From the data, we can calculate:
ÓX = (5+6+2+1)/4 = 14/4 = 3.5
ÓY = (8+10+5+6)/4 = 29/4 = 7.25
Ó(X+Y) = ÓX + ÓY = 3.5 + 7.25 = 10.75 which, when rounded off to the nearest integer, gives the answer as 14.
