Researchers measured skulls from different time periods in an attempt to determine whether interbreeding of cultures occurred. Results are given below. Assume that both samples are independent simple random samples from populations having normal distributions. Use a 0.05 significance level to test the claim that the variation of maximal skull breadths in 4000 B.C. is the same as the variation in A.D. 150 4000 B.C. A.D. 150 n 30 30 х 131.33 mm 136.49 mm 5.17 mm 5.31 mm SVOM What are the null and alternative hypotheses? O A. He: 04 = 0 H₂:0? 0? OC. He:0; -o Hg:0} <0? O B. Hoio+o Hy: 0; - OD. Ho: o = ož H4:0? 20 Identify the test statistic. F = (Round to two decimal places as needed.) Use technology to identify the P-value The P-value is (Round to three decimal places as needed.) What is the conclusion for this hypothesis test? O A. Fail to reject Ho. There is insufficient evidence to warrant rejection of the claim that the variation of O B. Reject Ho There is insufficient evidence to warrant rejection of the calm that the variation of maximal skull breadths in 4000 B.C. is the same as the variation in A.D. 150 maximal skull breadths In 4000 B.C. is the same as the variation in A.D. 150. O C. Reject Ho. There is sufficient evidence to warrant rejection of the clalm that the variation of maximal O D. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that the variation of skull breadths in 4000 B.C. is the same as the variation in A.D. 150. maximal skull breadths in 4000 B.C. is the same as the vanation in A.D. 150 Next
