Referring to the nano twisting data in Exercise 11.24, calculate the correlation coefficient.

Data From Exercise 11.24

Transcribed Image Text:

11.24 Nanowires, tiny wires just a few millionths of a centimeter thick, which spiral and have a pine tree-like appearance, have recently been created.2 The investigators' ultimate goal is to make better nanowires for high-performance integrated circuits, lasers, and biosensors. The twist, in radians per unit length, should follow a theory of mechanical deformation called Eshelby twist. The amount of twist should be linearly related to the reciprocal of cross section. The authors provided some of their data on y (rad/m) =twist and x (m-2) = reciprocal cross section.
