2) Below is an unidentified table of values: x 78 85 92 100 85 89 93 99 100 84 y 1. What is the key issue if these data are test grades of subjects before and after formal instruction? ("Is the instruction effective, as indicated by higher y scores?" See Section 9-4.) 2. What is the key issue if these data are reasoning tests for a sample of men (x)

2) Below is an unidentified table of values: x 78 85 92 100 85 89 93 99 100 84 y 1. What is the key issue if these data are test grades of subjects before and after formal instruction? ("Is the instruction effective, as indicated by higher y scores?" See Section 9-4.) 2. What is the key issue if these data are reasoning tests for a sample of men (x) and a separate sample of women (y)? ("Does the population of men have the same mean as the population of women?" See Section 9-3.) What is the key issue if each pair represents a math reasoning score x and a starting salary y in thousands of dollars? ("Is the starting salary associated with math reasoning?" See this chapter.) 3.
