4. People suspect that left-handed people are more likely to study STEM than other majors. A survey was conducted across several universities and the following data was found: STEM Non-STEM 45 147 192 Right Handed Left Handed 15 33 48 60 180 240 Does this data provide evidence that left handed people are more likely to study math and engineering? Which would be a valid null hypothesis to use? Handedness is related to the choice of major. The choice of major is related to handedness. Handedness and the choice of major are independent. Handedness is independent of major choice, but major choice is not independent of handedness. 5. Regardless of your answer above, let's say your p-value was 0.15. With alpha = 0.05, an appropriate conclusion from this test would be: We do not have evidence showing that left-handed people are more likely to study STEM than right handed people. We do have evidence showing that left-handed people are more likely to study STEM than right handed people. The expected numbers for each cell are not large enough to conduct the appropriate test and draw relevant conclusions. We observed that 25% of STEM majors are left-handed while only 18% of non-STEM are left-handed. Therefore, STEM majors are more likely to be left-handed.
