Problem 21 BB

Skull Measurements from Different Times Researchers measured skulls from different time periods in an attempt to determine whether interbreeding of cultures occurred. Results are given below (based on data from Ancient Races of the Thebaid,by Thomson and Randall-Maciver, Oxford University Press). Use a 0.05 significance level to test the claim that the variation of maximal skull breadths in 4000B.C.is the same as the variation ina.d.150.

4000b.c.(Maximal Skull Breadth): n=30,x=131.37 mm,s=5.13 mm

a.d.150 (Maximal Skull Breadth): n = 30,x =136.17 mm,s =5.35 mm

Step-by-Step Solution:
Step 1 of 3

Problem 21 BB

Answer:

Step1 of 3:

We have from Different Times Researchers measured skulls from different time periods in an attempt to determine whether interbreeding of cultures occurred. Results are given below (based on data from Ancient Races of the Thebaid,by Thomson and Randall-Maciver, Oxford University Press).

4000b.c.(Maximal Skull Breadth): =30,=131.37 mm,=5.13 mm

a.d.150 (Maximal Skull Breadth):  = 30, =136.17 mm, =5.35 mm

Step2 of 3:

We need to test the claim that the variation of maximal skull breadths in 4000B.C.is the same as the variation in a.d.150 by using level of significance.

Step3 of 3:

The appropriate null and alternative hypothesis are given by
