Thank you for the opportunity to help you with your question! Hi, He observes that work expands so as to fill the time available for its completion.

sample size is a very important feature in any empirical data analysis. its very important as it helps in making

the formulas used are

ss=Z^2* (p) * (1-p)/c2

Z = Z value (confidence level)
p = percentage picking a choice, expressed as decimal
(.5 used for sample size needed)
c = confidence interval, expressed as decimal

for a finite population we will have

new ss=ss/ss-1/1+pop

pop refers to population
