Problem 17BSC

BSC use the indicated Data Sets from Appendix B. Assume that both samples are independent simple random samples from populations having normal distributions. Weights ?Repeat Exercise using all of the weights listed in Data Set 1 in Appendix B. Exercise Weights ?Listed below are weights (kg) of randomly selected females and males taken from Data Set 1 in Appendix B. Use a 0.05 significance level to test the claim that males have weights with more variation than females. Female: 59.3 74.5 77.7 97.9 71.7 60.9 60.5 88.2 43.8 47.9 Male: 64.4 61.8 78.5 86.3 73.1 58.5 134.3 79.8 64.8 58.1

Step-by-Step Solution:

Solution 17 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 n 140 Males : s1=18.5281 n 240 Females : s2=20.6883
