Answer:
Sample proportion ; phat
x / n
Step-by-step explanation:
The sample proportion may be explained as a proportional representation of part of the population or larger sample which have a certain character or exhibit a particular trait.
The sample proportion is expressed Mathematically as ;
phat = x / n
x = number of subjects with a specified characteristic ;
n = total sample size
For instance ;
The proportion of black balls in a sample of 100 balls is 15 ; the sample proportion of bla k balls will be :
phat = x / n = 15 / 100 = 0.15
Local(L) = 1 x (15.99)
Online(O) = (1 x 13.99) + 6
So use that equation until you find the same number.
L1=15.99
O1=19.99
L2=31.98
O2=33.98
L3=47.97
O3=47.97
And your answer will be three from local and three from online.
