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
