1. In order to estimate the proportion of women over 50 who have annual mammograms with a95% confidence interval to within 0.05, how many women must you interview? Assume thatyou estimate the proportion might be 0.6.p=.6z=1.962. Resource-selection analysis compares the distributions of animals relative to the distributionof habitat. If the two don’t agree, there is evidence of selection. A survey of 106 moosefound that 24 were located in “In burn – interior,” 22 in “In burn – edge,” 20 in “Out of burn– edge,” and 40 in “Other” habitat types. The corresponding proportion of the landscape asdetermined by a Geographic Information System (GIS) in these habitats was 0.340, 0.101,0.104, and 0.455 respectively.a) What is the null and alternative hypothesis?Ho=in burn interior=.34, in burn edge=.101, out of burn edge=.104, andother=.455Ha= not in burn interior=.34, in burn edge=.101, out of burn edge=.104,and other=.455b) Complete the chi-square GOF tableCategoriesobservation(expectation)In burn-interior24In burn-edge22Out of burn20other40
