1. An automotive part must be machined to close tolerances to be acceptable to customers. Production specifications call for a maximum variance in the lengths of the parts of 0.0004. Suppose the sample variance for 30 parts turns out to be s2 =0.0005. Use a=0.05 to test whether the population variance specification is being violated. Identify the alternative hypothesis? (3 Points) Ha: sigma^2>0.0004 Ha: sigma^2<0.0004 Ha: sigma^2 = 0.0004 None of the above
