Our professor wants us to calculate the test statistic and p-value by hand. The test statistic is correct. I can't get the p-value to save my life. Do you know what I am doing wrong?? (All of these p-value answers are incorrect: 0.25, .1230, 2.32, .0232, .02, and .01) An article published in the Washington Post claims that 45 percent of all Americans have brown eyes.

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
