Assume that there is a positive linear correlation between the variable R
(return rate in percent of a financial investment) and the variable t(age in years of the investment) given
by the regression equation R=2.5t+5.3.
(a) Without further information, can we assume there is a cause and effect relationship between the
return rate and the age of the investment?
(b) If the investment continues to grow at a constant rate, what is the expected return rate when the
investment is 7 years old?
(c) If the investment continues to grow at a constant rate, how old is the investment when the return
rate is 32.8%?
