You have heard that in sports like boxing there might be some competitive advantage to those wearing red uniforms. You want to test this with your new favorite sport of chess-boxing. You randomly assign blue and red uniforms to contestants in 20 matches and find that those wearing red won 14 times (or 70%). You conduct a test of significance using simulation and get the following null distribution. (Note this null distribution uses only 100 simulated samples and not the usual 1000 or more.) Probability of success (π): 0.5
Sample size (n): 20
Number of samples: 100
Total = 100

Suppose you want to see if competitors wearing red win more than 50% of the matches in the long run, so you test H0: π= 0.50 versus Ha: π > 0.50. What is your p-value based on the above null distribution? Suppose you now want to see if competitors wearing either red or blue have an advantage, so you test H0: π= 0.50 versus Ha: π ≠ 0.50. What is your p-value now based on the above null distribution?

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
