Step-by-step explanation:
1) The statement is true. A larger margin of error creates a wider confidence interval, which is more likely to contain the population parameter.
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.
Answer:
your answers should be 4, 4, 12, 1/12. in that specific order. the first one is wrong because if it was 12 thirds there would be 36 equal parts. Hope this helps. :)
