Two students conduct a study to investigate the relationship between forearm length and height. Maria measures the subjects in centimeters. In a scatterplot of the data she sees a linear relationship between the variables, so she calculates the correlation coefficient. She determines that r = 0.86. John measures the same subjects in inches. He also calculates the correlation coefficient. What do you expect the correlation will be for John's measurements? O John's correlation will be approximately 0.86(0.61) = 0.52 because one centimeter - 0.61 inches O John's correlation will be approximately r = 1 because there is a very strong relationship between John's measurements and Maria's measurements. O John's correlation will be approximately 0.86 because the pattern in the data will be the same
