Title: If a data set has a relationship that is best described by a linear model, than the residual plot will
Post by: OSWALD on Aug 30, 2019

Question 1

We can use the length of a man’s hand span to predict his height, with a correlation coefficient of r = 0.60. If we change our measurements from cm to m, the new correlation will be
◦ 0.60
◦ 0.006
◦ none of these
◦ 0.06
◦ 6

Question 2

If a data set has a relationship that is best described by a linear model, than the residual plot will
◦ be an unknown shape.
◦ have a curved pattern, like a parabola.
◦ also have a linear pattern with a similar correlation.
◦ none of these
◦ have no pattern with a correlation near 0.
