For this homework we will consider the dataset on Deaths in Car Accidents (2002).
Problem 1: Find the least squares regression line (the equation) of FemaleAccidents (=y) by MaleAccidents (=x). Are all the assumptions of least squares regression justified?
Problem 2: Use the equation from 1) to predict the number of FemaleAccidents when there are 550 MaleAccidents
Problem 3: The different age groups have very different population sizes, so it maybe better to base this analysis on percentages rather than totals. Find the least squares regression line of Percentage of FemaleAccidents (=y) by Percentage of MaleAccidents. Include the fitted line plot in your solution. Check all the assumptions and write down what you find..
Problem 4: The simple scatterplot of Percentage of FemaleAccidents vs. Percentage of MaleAccidents is this:
This graph has a serious flaw: it makes it look like as if the increase in percentages for Males and Females is the same. A better graph is the following:
Draw this graph, with the least squares regression line as shown and your name below the title.
