Artificial hip joints consist of a ball and socket. As the joint wears, the ball (head) becomes rough. Investigators performed wear tests on metal artificial; hip joints. Joints with several different Diameters were tested. The following table presents measurements of head roughness (in Nanometers). Perform the Tukey-Kramer test to determine which pairs of means, if any, differ. Use the $\alpha = 0.01$ level of Significance.
A) There is not enough evidence to conclude that any of the means differ.
B) $\mu _ { 16 } \neq \mu _ { 24 } , \mu _ { 16 } \neq \mu _ { 30 }$
C) $\mu _ { 16 } \neq \mu _ { 24 }$
D) $\mu _ { 16 } \neq \mu _ { 24 } , \mu _ { 24 } \neq \mu _ { 30 }$
