Generally, is n30 iconsidered the lower limit for large sample size?

Solution

YES, IT IS

GENERALLY N = 30 IS THE LOWER LIMIT FOR A LARGE SAMPLE SIZE

IF YOU NEED TO USE Z OR T DISTRIBUTION FOR A HYPOTESIS OR A CONFIDENCE INTERVAL IT DEPENDS IN IF YOU KNOW THE STANDARD DEVIATION SAMPLE OR STANDARD DEVIATION POPULATION

AND IF YOU HAVE A LARGE SAMPLE SIZE

THE BOOKS GENERALLY USE N> 30 AND YOU WILL CONSIDER YOUR SAMPLE SIZE AS LARGE ENOUGH

BUT THIS IS RELATIVE BECAUSE IT SAID WHEN YOU HAVE N BIGGER

BIGGER FOR STATISTCS IS RELATIVE

YOU CAN HAVE A SAMPLE SIZE OF 500 AND FOR YOU IS BIGGER

YOU CAN HAVE A SAMPLE SIZE OF 5 AND POPULATION 10 SO YOUR SAMPLE SIZE IS BIGGER

BUT IF YOU CONSIDER ALL BOOKS OF STATISTICS SO THE ANSWER IS YES

WE CONSIDERED THE LOWER LIMIT FOR A LARGE SAMPLE SIZE N=30
