Question

To test $H_0: \sigma = 2.4$ versus $H_1: \sigma > 2.4$, a random sample of size $n = 21$ is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be $s = 3.3$, compute the test statistic. (b) If the researcher decides to test this hypothesis at the $\alpha = 0.05$ level of significance, use technology to determine the P-value. (c) Will the researcher reject the null hypothesis? (a) The test statistic is $\chi^2_0 = \Box$. (Round to two decimal places as needed.) (b) The P-value is $\Box$. (Round to three decimal places as needed.) (c) Since the P-value is $\Box$ than the level of significance, the researcher $\Box$ reject the null hypothesis $H_0: \sigma = 2.4$.
