Below are a set of heights (in inches) and GPA scores for a sample of 6 students Height GPA 60 55 3.2 62 58 49 61 4.0 3.7 3.9 2.4 2.8 a. Find the correlation coefficient (r) for these two variables by hand: Find the mean and standard deviation for each variable Find the equation of the regression line to predict GPA from height by hand: Find the equation of the regression line to predict height from GPA by hand b. c. d. and e. Based on this data, what is the GPA prediction for a student who is 56 inches tall? f How good is this prediction?

The equation shown below represents function f. f(x)= -2x+5 the graph shown below represents function g. which of the following statements is true? a. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is less than the y-intercept of function g. b. over the interval [2, 4], the average rate of change of f is greater than the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. c. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. d. over the interval [2, 4], the average rate of change of f is less than the average rate of change of g. the y-intercept of function f is the same as the y-intercept of function g.
