A manager wishes to estimate an average cost equation of the following form: $C = a + b Q + c Q ^ { 2 }$ where Q is the level of output.Letting Z = Q² and using least-squares estimation,the manager obtains the following computer output: Given the above information,which of the parameter estimates are statistically significant at the 1% significance level? A)All parameter estimates are statistically significant. B)All parameter estimates except $\hat { b }$ are statistically significant. C) $\hat { a }$ is not statistically significant,but all the rest of the parameter estimates are significant. D) $\hat { C }$ is not statistically significant,but all the rest of the parameter estimates are significant.
