Test the claim about the differences between two population variances o; and oz at the given level of significance a using the given sample statistics. Assume that the sample statistics are from independent samples that are randomly selected and each population has a normal distribution Claim: of>o a= 0.05 Sample statistics: s2 = 653, n = 10,5 = 4 = 489, n2 = 12 .. Find the null and alternative hypotheses. O A. Ho: 0; >o Ha o so S O B. Ho:04 20 Ha:ofco O D. Hoioso Ha: 0; > o O C. Ho dº <o Haio 20 Find the critical value (Round to two decimal places as needed.) Find the test statistic. (Round to two decimal places as needed.) Choose the correct conclusion below. O A. Reject the null hypothesis. There is enough evidence to reject the claim. OB. Fail to reject the null hypothesis. There is not enough evidence to support the claim. O C. Fail to reject the null hypothesis. There is not enough evidence to reject the claim OD. Reject the null hypothesis. There is enough evidence to support the claim.
