35. Transformed Data In addition to testing for a linear correlation between x and y, we can
often use transformations of data to explore other relationships. For example, we might replace
each x value by x and use the methods of this section to determine whether there is a linear
correlation between y and x². Given the paired data in the accompanying table, construct the
scatterplot and then test for a linear correlation between y and each of the following. Which
case results in the largest value of r?
а. X

50
95
y
0.3
0.5
