As part of an evaluation program, a sporting goods retailer wanted to compare the downhill coasting speeds of four brands of bicycles. She recorded three trials of each brand and determined their maximum downhill speeds. The results are presented in kilometres per hour in the table below.
$$\begin{array} { | l | l | l | l | l | } \hline \text { Trial } & \text { Barth } & \text { Tornado } & \text { Reiser } & \text { Shaw } \\\hline 1 & 43 & 37 & 41 & 43 \\\hline 2 & 46 & 38 & 45 & 45 \\\hline 3 & 43 & 39 & 42 & 46 \\\hline\end{array}$$
-Referring to Instruction 11-3,the null hypothesis for Levene's test for homogeneity of variances is

• A) \(H _ { 0 } : { \sigma _ { A } ^ { 2 } } = { \sigma _ { B } ^ { 2 } } = { \sigma _ { C } ^ { 2 } } = { \sigma _ { D } ^ { 2 } }\)
• B) H 0 : \(\mu\) A = \(\mu\) B = \(\mu\) C = \(\mu\) D
• C) H 0 : \(\pi\) A = \(\pi\) B = \(\pi\) C = \(\pi\) D.
• D) H 0 : M A = M B = M C = M D.
