Question

True/False :

a.   In a scatterplot, the response is shown on the horizontal axis with the explanatory variable on the vertical axis.

b. The symbols b0 and b1 represent the sample intercept and the sample slope, respectively.

c. A correlation of 0.8 implies two variables are more strongly related than if the correlation between the two variables was -0.8.

d. If we reverse the role of x and y (that is x becomes the response and y becomes the explanatory variable) we will get the same least squares regression line.
