question 50

Multiple Choice

In a hypothesis test for the population variance, the hypotheses are: $H _ { 0 } : \sigma ^ { 2 } = 175$ $H _ { 1 } : \sigma ^ { 2 } \neq 175$ If the sample size is 25 and the test is being carried out at the 5% level of significance, the rejection region will be:

• A) \(\chi ^ { 2 }\) < 15.6587 or \(\chi ^ { 2 }\) > 33.1963.
• B) \(\chi ^ { 2 }\) <12.4011 or \(\chi ^ { 2 }\) >39.3641.
• C) \(\chi ^ { 2 }\) < 16.4734 or \(\chi ^ { 2 }\) >34.3816.
• D) \(\chi ^ { 2 }\) < 13.1197 or \(\chi ^ { 2 }\) <37.6525.
