Answer:

A. 0.949

Explanation:

Use your favorite calculator or spreadsheet to compute the correlation coefficient.

r ≈ 0.949

_____

Additional comment

The values of y generally increase as the values of x increase--with only one exception. This tells you the correlation coefficient is positive and fairly high. Of the two positive choices 0.901 and 0.949, the higher one is the better guess.
