In аstrоnоmy clаss, Jill leаrned that blue stars are hоtter than white stars. She also learned that white stars are hotter than red ones. The next day, when asked to identify the cooler star when given the choice between red versus blue, Jill correctly selected the red star. Which of the following did Jill demonstrate?

BACKGROUND: A representаtive sаmple оf Americаn adults were asked a set оf questiоns about their social values. Below I have provided the linear regression output specifying the relationship between level of political identity (POLID) and views about gender equality (GENDERVIEW). How does a person's political identity impact their beliefs about gender equality? POLID is based on the following question: "In political matters, people talk of "the left" and "the right." How would you place your views on this scale, generally speaking?" POLID is measured on a scale of 1 to 10 (1 = Left; 10 = Right). GENDERVIEW is based on the following question: "Please tell me for each of the following things how essential you think it is as a characteristic of democracy. Women have the same rights as men." GENDERVIEW is measured on a scale of 1 to 10 (1 = not essential; 10 = essential). The sample size is n = ~2410 (some cases are dropped for analytical ease). ESSAY REQUIREMENTS (Use these numbers to organize your answer): Describe the data. Using the mean and standard deviations, how would you interpret Americans' beliefs in gender equality being essential to democracy? Regression equation. Using the SPSS output, please write out the linear equation representing this relationship. Provide an interpretation in one sentence describing how the dependent variable changes for every unit increase or decrease in the independent variable. Predicted value. Compute the predicted value of GENDERVIEW when a person has a far-right political identity: POLID = 9.5. Provide an interpretation in a sentence. Statement of correlation. Report and label the correlation coefficient (Pearson’s r). Using appropriate statistical language, provide an interpretation of this coefficient.
