A high school guidance collected the following data about the grade point averages (GPA) and the SAT mathematics test scores for six seniors. GPA | 2.7 | 3.5 | 3.4 | 3.3 | 3.6 | 3.0 SAT | 450 | 560 | 700 | 620 | 640 | 570 a) Develop a scatter diagram for the data with GPA on the horizontal axis. b) Compute the correlation coefficient for the data. What does this value tell us about the relationship between the two variables?

The scatterplot illustrates the relationship between high school and college GPAs for a sample of students. Relationship between High School and College GPAs Which of the following is an accurate description of the scatterplot? Students with higher high school GPAs have higher college GPAs: Students with lower high school GPAs repeat their performance and get low college GPAs. Because college is a fresh start; there is no relationship between high school and college GPAs_ Lower high school GPAs correlate to lower college GPAs, with one exception of a low high school GPA and high college GPA

Draw a scatter diagram for each given data set. Use graph paper. From your graph determine whether there is a linear relationship between the variables. $$\begin{array}{|c|c|}\hline & \text { Grade } \\\text { ACT } & \text { Point } \\\text { Score } & \text { Average } \\\hline 18 & 2.2 \\26 & 3.4 \\20 & 2.8 \\17 & 2.0 \\19 & 2.6 \\23 & 3.2 \\25 & 3.6 \\30 & 4.0\\\hline\end{array}$$

The following table presents the Grade-Point Average (GPA) and Family Income of 8 students. GPA | Family Income (in $1000) (X) --------------------------------------- 4.0 | 21 3.0 | 15 3.5 | 15 2.0 | 9 3.0 | 12 3.5 | 18 2.5 | 6 2.5 | 12 A) Calculate the correlation coefficient between GPA and Family Income. B) Comment on the relationship. C) Fit a linear regression line of GPA on Family Income.
