Question
(f) T F A correlation of 0.8 implies two variables are more strongly related than if the corre- lation between the two variables were -0.8 (g) T F The least squares regression line always passes through the point (,7). (h) T F High correlation implies causation. (i) T F If we reverse the role of r and y (that is, y becomes the explanatory variable and r becomes the response variable) we will get the same least squares regression line (j) T F If no data points deviate from a single line with nonzero slope, then the correlation coefficient of the fitted regression model is 1. (Assume the values of the explanatory variable are not identical (k) T F When an observation falls above the least squares regression line its residual is always positive.Explanation / Answer
f) this is false as strength depend on absolute value
g) true ; as equation intercept is based on thses two points
h) false
i) false
j)true
k) true as residual =actual-predicted which is postiive if observation falls above line
