Lynna [10]

Answer:

  1. A
  2. A

2) The statement is false. A larger sample size decreases the standard error of the sample proportion, which decreases the margin of error.

3)  The statement is true. A smaller sample size increases the standard error of the sample proportion, which, for a fixed margin of error, decreases the critical value, z*.

4)  The statement is true. One can see from the margin of error formula that the margin of error is inversely proportional to the square root of n.
