Solution 16 BSC Step 1 The given problem explain about weights of females and males . Then we have selected randomly females and males weights. From the given information we want to test the claim that males have weights with more variation than females. Here, first sample is males group because its standard deviation is larger and second sample is females group. Then hypothesis is H 0 =1 2 H 1 > 1 2 Where a1d ar2 the variance of population. Then the given data is Weight n1=10 Males : s1=22.6627 n2=10 Females : s2=17.0734
