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 Right Handed 45 147 192 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. Symbollically, which of the following would be an appropriate null hypothesis? O Pr(Left Handed | STEM) = Pr(Right Handed | STEM) Pr(STEM Left Handed) = Pr(Left Handed | STEM) O Pr(Non-STEM Right Handed) = Pr(STEM Left Handed) Pr(Right Handed | STEM) = Pr(Right Handed Non-STEM) 6. What is the value of the test statistic? 7. What is the p-value? 01.25 O 0.1
