Don 4-15-05 Statistics 427 Assignment 6 Spring 2005 1) Define two population mean diameters at breast height: one, denoted by μ A , for site A and one, denoted by μ Β , for site B. Be sure to explain exactly which population of trees these means correspond to. Let X 1 denote the diameter at breast height (DBH) of the Site A and X 2 denote the diameter at breast height (DBH) of Site B. Therefore, we will test the research hypothesis H1: μ 1< μ 2, where μ 1 denotes the population mean of site A which is the diameter at breast height (DBH) of the Banksia trees who where burned more frequently during this period and μ 2 denotes the population mean of site B which is the diameter at breast height (DBH) of the Banksia trees who where burned infrequent during this period. 2) Formalize the contention from above as a research hypothesis relating μ a and μ b. State the hypothesis in words (in the context of this study) and also in terms of the symbols μ a and μ b. Briefly justify your choice of this research
