In the 1990s, studies showed that about 9 out of 10 Americans would vote for a woman for president. Data from the 2010 General Social Survey shows that 1,357 of 1,411 respondents would vote for a woman for president. Is this a significant increase over the 1990s, or could it be due to sample variability?

A

Accept the null as true since the sample proportion is close to the claimed proportion. The p-value is too large to calculate.

B

Reject the null. Since the p-value is very small, less than 0.0001, the observed increase isn't likely due to sample variability alone. The proportion of Americans who would vote for a woman for president is greater than 90%.

C

These data are inconclusive. You can't perform a test here because there weren't at least 15 successes and 15 failures.

D

Don't reject the null. Since the p-value is very small, less than 0.0001, the observed increase is likely due to sample variability alone. The proportion of Americans who would vote for a woman for president according to the GSS isn't significantly greater or less than 90%.
