47. The density of mercury at several selected temperatures is known as follows
r(°C)
-10.00
0.00

d (g/ml)
13.6202 13.5955 13.5708 13.5462 13.5217 13.4973 13.4729
(a) Using the method of least squares, find the mathematical equation that
best fits these data (see pp 72-75).
(b) Find the correlation coefficient and the 95% confidence intervals for both
the slope and the intercept of the best-fit equation found in (a).
