Question

Only the questions after "State the critical values for the rejection rule..." and after. So only questions in secound image. Thank you. 

State the critical values for the rejection rule. (Round your answers to three decimal places. If the test is one-tailed, enter NONE for the unused tail.)
test statistic <
test statistic >
State your conclusion.
Reject Ho. We conclude that the population variance is greater than 50.
Do not reject Ho. We conclude that the population variance is greater than 50.
Reject Ho. We conclude that the population variance is not greater than 50.
Do not reject Ho. We conclude that the population variance is not greater than 50.
