In a Goodness-Of-Fit Test, the Null Hypothesis States That the Data

In a goodness-of-fit test, the null hypothesis states that the data came from a normally distributed population. The researcher estimated the population mean and population standard deviation from a sample of 500 observations. In addition, the researcher used 6 standardised intervals to test for normality. Using a 5% level of significance, the critical value for this test is: $$\begin{array} { | l | l | } \hline \text { A. } & 11.1433 . \\\hline \text { B. } & 9.3484 . \\\hline \text { C. } & 7.8147 . \\\hline \text { D. } & 9.4877 . \\\hline\end{array}$$
