Select one:

a. Thecomputations are wrong since coefficient of correlation cannot be negative.b. There is a fairly low relationship between the two variables.c. The coefficient of determination is the square root of 0.90.d. Variable Y tends to decrease as variable X increases.e. The slope in corresponding simple linear regression model must be positive.
