Following is a simple linear regression model:

The following results were obtained from some statistical software.
R2 = 0.523
syx (regression standard error) = 3.028
n (total observations) = 41
Significance level = 0.05 = 5%

Variable Parameter Estimate    Std. Error of Parameter Est.

Intercept 0.519    0.132

Slope of X    -0.707 0.239

Questions: the correlation coefficient r between the x and y is? What is the meaning of R2? Show your work.

In a simple linear regression, the following sample regression equation is obtained: yˆ=407−21x.y^=407−21x. a. Interpret the slope coefficient. As x increases by 1 unit, y is predicted to decrease by 21 units. As x increases by 1 unit, y is predicted to increase by 21 units. As x increases by 1 unit, y is predicted to decrease by 407 units. As x increases by 1 unit, y is predicted to increase by 407 units. b. Predict y if x equals...

Data on the water quality in the eastern United States was obtained by a researcher who wanted to ascertain whether or not the amount of particulates in water (ppm) could be accurately used to predict water quality score. Suppose we fit the following simple linear regression model: Qualityi = ? 0 + ? 1 × particulatesi + ? i where the deviations ?i were assumed to be independent and Normally distributed with mean 0 and standard deviation ?. This model...
