1) You are given a regression equation for the relationship between a local music stores sales (y) and expenditure on advertising (x) both measured in thousands of dollars ($000s). It is (y-hat) = 25 + 0.85 x Interpret this equation. Select one: a. The slope is 25 and the intercept is 85. This means that with 0 advertising the sales would be $25,000 and each $1,000 in advertising yields $850 in sales. b. The slope is 0.85 and the intercept is 25. This means that with 0 advertising the sales would be $25,000 and each $1,000 in advertising yields $850 in sales. c. The slope is 0.85 and the intercept is 25. This means that with 0 advertising the sales would be $850 and each $1,000 in advertising yields $2,500 in sales. d) The slope is 25 and the intercept is .85. This means that with 0 advertising the sales would be $25,000 and each $1,000 in advertising yields $850 in sales. 2) In terms of bivariate analysis, classify height and weight as either dependent or independent variables. Select one: a. Height: Dependent Weight: Dependent b. Height: Independent Weight: Independent C. Height: Dependent Weight: Independent d. Height: Independent Weight: Dependent 3) Which of the following is not a definition of probabilistic independence? Select one: a. Events A and B are independent if, and only if, they do not impact each other's probability b. P(A]B) =P(A) C. Event A is independent of event B if the occurrence of B does not impact A d. P(A and B) =P(A)P(B) 4) Classify each of the following probability values as either (valid or invalid) P(X) = 1.00 P(X) = 0.89 P(X)=-1.52 P(X)=-0.35 P(X) = 0.65 P(X) =0.6x P(X) = 1.52 P(X) = 0.00 5) The complement of a probability is Select one: a. the sum of all other probabilities in its sample space. b. when the opposite outcome occurs. C. when you let it know if it's looking cute, or similar
