Unformatted text preview: between TOST time and RBOT time. (b) The value of r does not depend on which of the two variables is labeled as the x variable. Thus, had we let x = RBOT time and y = TOST time, the value of r would have remained the same. (c) The value of r does not depend on the unit of measure for either variable. Thus, had we expressed RBOT time in hours instead of minutes, the value of r would have remained the same. Problem 3.16 The value of the sample correlation coefficient using the squared y values would not necessarily be approximately 1. If the yvalues are greater than 1, then the squared yvalues would differ from each other by more than the yvalues differ from one another. Hence, the relationship between x and y 2 would be less like a straight line, and the resulting value of the correlation coefficient would decrease....
