Problem 17 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
