Research performed at NASA, led by Dr. Emily R. Morely-Holton, measured the lengths of the right humerus and right tibia in 11 rats that were sent to space on Space Lab Life Sciences. See Table 1.
Right Humerus (mm) x | Right Tibia (mm) y
24.80 | 36.05
24.59 | 35.57
24.59 | 35.57
24.29 | 34.58
23.81 | 34.20
24.87 | 34.73
25.90 | 37.38
26.11 | 37.96
26.63 | 37.46
26.31 | 37.75
26.84 | 38.50
Table 1: Lengths of Humerus and Tibia in Space Rats
1. Make a scatter plot of the data, treating the length of the right humerus as the independent variable.
2. Based on the scatter plot, do you think that there is a relation between the length of the right humerus and the length of the right tibia? If yes, what type of relation?
