The committee decided to focus on the number of police officers in the city, the percentage of arrested men who tested positive for drugs, the number of families in the city below the poverty level, the number of people between 16 and 19 who were not enrolled in school and were not high school graduates and the number of single-female-parent households. They were focusing on 23 large cities but not all of the data were available for all of the cities in the study. (a) The committee want to find a model that will predict the number of serious crimes from one of the other chosen variables. They initially choose "number of male arrests for drugs." Use Data Analysis in Excel to investigate this linear regression model and use it to write one sentence to summarise how good a predictor "male arrests for drugs" is. You do not need to include the full regression output but you do need to state clearly the value of any coefficients you have used to make your decision.
