Problem 12BSC

BSC Skull Measurements? from Different TimesResearchers measured skulls from different time periods in an attempt to determine whether interbreeding of cultures occurred. Results are given below (based on data fromAncient 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:

Solution 12 BSC Step 1 The given problem explain about skull measurements. From the given information we know that we want 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. Here, first sample is A.D. 150 group because its standard deviation is larger and second sample is 4000 B.C. Then hypothesis is H 0 =1 2 H 1 = 1 / 2 Where and are the variance of population. 1 2 Then the given data is Maximum Skull Breadth n1=30 A.D. 150 : x = 136.17 mm 1 s1=5.35 mm n2=30 4000 B.C. : x2=131.37 mm s2=5.13 mm
