In a Hypothesis Test for the Population Variance, the Hypotheses $H _ { 0 } : \sigma ^ { 2 } = 25$

question 60

Short Answer

In a hypothesis test for the population variance, the hypotheses are: $H _ { 0 } : \sigma ^ { 2 } = 25$ . $H _ { 1 } : \sigma ^ { 2 } > 25$ . If the sample size is 15 and the test is being carried out at the 5% level of significance, the null hypothesis will be rejected if: $\begin{array}{|l|l|}\hline A&\chi^{2}<6.5706\\\hline B&\chi^{2}>24.9958 \\\hline C&\chi^{2}<7.2609\\\hline D& \chi^{2}\text {>23.6848}\\\hline\end{array}$
