Question 985838: The least-squares regression line (line-of-best-fit) for volume (in millions of shares) of a company's stock as a function of time is given by S(t) = 18-0.46t, t months after the beginning of the year. The linear correlation coefficient relating stock and time is -0.88.
a) Is the linear relationship between the two variables strong or weak?
b) Is the linear relationship positive or negative?
c) What does the model predict the volume of the stock will be at the end of the year? Answer by jim_thompson5910(35256) (Show Source):
