given values: 99% confidence level, 7 and E2.7. If the confidence level is lowered to 90% what will be the appropriate sample size?A. 34B. 35C. 36D. 37
Added by Neo S.
Step 1
A higher confidence level requires a larger sample size and vice versa. The formula to calculate the sample size is: n = (Z^2 * p * (1-p)) / E^2 where: n = sample size Z = Z-score (which corresponds to the desired confidence level) p = estimated proportion of Show more…
