Question

To calculate z score , you have to know the raw score , population mean , and standard deviation. Of the following what matches with the three ; Sample proportion , Sample size , wnd Popularion proportion .

Answer 1

The formual for z-score is

Z-score = (X - ) /

Where X is raw score

is population mean

is standard deviation

The formual for z-score is

z-score = ( - p₀) / p₀ * (1 - p₀) / n

is the sample proportion

p₀ is the population proprtion

n is the sample size

So raw score matches with Sample Porportion

Population Mean matches with Population Proportion

Standard Deviation matches with Sample size
