Question

question 10 (1 point) increasing the confidence level while keeping the same sample size has what effect on the margin of error? decreases the margin of error and hence decreases the precision decreases the margin of error and hence increases the precision increases the margin of error and hence decreases the precision increases the margin of error and hence increases the precision

Explanation:

The margin of error formula is related to the z - score (which depends on the confidence level). As the confidence level increases, the z - score increases. With a fixed sample size, a larger z - score leads to a larger margin of error. A larger margin of error means less precision in our estimate.

Answer:

Increases the margin of error and hence decreases the precision
