Question

. If all other sample size planning factors were exactly the same in attribute sampling, changing the confidence level from 95% to 90% and changing the desired precision from 2% to 5% would result in a revised sample size that is

A. Larger.

B. Smaller.

C. Unchanged.

D. Indeterminate.

Answer 1

If all other sample size planning factors were exactly the same in attribute sampling, changing the confidence level from 95% to 90% and changing the desired precision from 2% to 5% would result in a revised sample size that is

C.Unchanged

Because changing the confidence level from 95% to 90% results in larger sample size on the other hand changing the desired precision from 2% to 5% results in a smaller sample size because you can accept more error.

So, the resultant sample size is unchanged.
