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.

What are the null and altemative hypotheses?
O B. Ho: o =03
O A. Ho: 0 =0}
H: 0?203
OC. Ho o *03
O D. Ho: g =03
Identify the test statistic.
=(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 O B. Reject Ho. There is insufficient evidence to warrant
rejection of the claim that the variation of maximal skull
breadths in 4000 B.C. is the same as the variation in A.D.
