Answer:

Plot the points on the graphing calculator. Then generate a line of best fit and a correlation coefficient.

x = number of years since 1990

y = pupil-teacher ratio

a) y = -.1175x + 15.74

b) If x = 30, then y = 12.215. This ratio seems realistic.

c) r = -.9326, a very strong negative correlation.
