Answer questiоn 1 Pаrts A-H belоw using the infоrmаtion Below: We will consider the crime dаtaset presented in Statistical Methods for Social Sciences, Third Edition, by Alan Agresti and Barbara Finlay (Prentice Hall, 1997). The variables are state name (state), violent crimes per 100,000 people (crime), murders per 1,000,000 (murder), the percent of the population living in metropolitan areas (pctmetro), the percent of the population that is white (pctwhite), percent of the population with a high school education or above (pcths), percent of the population living under the poverty line (poverty), and percent of the population that is single parents (single). The objective is to develop a model for crime rate (crime) using some of the predictors. The first few observations are given below. state crime murder pctmetro pctwhite pcths poverty single 1 ak 761 9 41.8 75.2 86.6 9.10 14.3 2 al 780 11.6 67.4 73.5 66.9 17.4 11.5 3 ar 593 10.2 44.7 82.9 66.3 20 10.7 4 az 715 8.60 84.7 88.6 78.7 15.4 12.1 Consider the following analysis done in R.
