a.

To conduct a follow-up study that would provide 95% confidence that the point estimate is correct to within
plus or minus ±0.05 of the populationproportion, how large a sample size is required?

A sample size of nothing people is required.

(Round up to the nearest integer.)

b.

To conduct a follow-up study that would provide 99% confidence that the point estimate is correct to within

plus or minus ±0.05 of the populationproportion, how many people need to be sampled?

A sample size of nothing people is needed. (Round up to the nearest integer.)

c.

To conduct a follow-up study that would provide 95% confidence that the point estimate is correct to within

plus or minus ±0.02 of the populationproportion, how large a sample size is required?

.d.

To conduct a follow-up study that would provide 99% confidence that the point estimate is correct to within

plus or minus ±0.02 of the populationproportion, how many people need to be sampled?

.e.

A. The higher the level of confidence desired, the larger is the sample size required.

B. The smaller the sampling errordesired, the larger is the sample size required.

C. The higher the sampling errordesired, the larger is the sample size required.

D. The smaller the sampling errordesired, the smaller is the sample size required.

E. The smaller the level of confidence desired, the larger is the sample size required.

F.

The higher the level of confidence desired, the smaller is the sample size required.
