Chapter 2, Problem 23(choose chapter or problem)
Consider the data set from Exercise 17. a. Reverse the roles of x and y so that now y is the explanatory variable and x is the response variable. Create a scatterplot for the ordered pairs of the form (y, x) using this data set. b. Compute r. How does it compare to the r-value from Exercise 17? Why does this make sense? c. The best fit line for the scatterplot in (a) will be of the form x my b. Determine this line. d. Using the line from (c), find the predicted x-value for the following y-values, if appropriate. If it is not appropriate, tell why. i. y 23 ii. y 2 iii. y 16 24.
