Suppose a 99% confidence interval was computed based on a sample of size 28. If the sample size were decreased to 20, what impact would this have on the margin of error and width of the confidence interval?

Suppose a 99% confidence interval was computed based on a sample of size 28. If the sample size were decreased to 20, what impact would this have on the margin of error and width of the confidence interval?

Both the margin of error and the width would increase.

Neither the margin of error nor the width would be affected.

The margin of error would increase and the width would decrease.

Both the margin of error and the width would decrease.
