Refer to figures (A) and (B) above.

a. Compare the percentages of heads in figures (A) and (B).

b. Calculate the standard error for the proportion of heads when tossing a fair coin 50 times. Then find the standard error for the proportion of heads when tossing a fair coin 200 times.

c. When using the CLT for one sample proportion, If you increase the sample size, the standard error will ________________ (increase or decrease), which makes the z-score ____________________________ (closer to zero or farther from 0), and that makes the tail area(s) ________________ (larger or smaller).
