1. The following data shows the number of miles driven and advertised price for 11 used Honda CR-Vs from the 2005- 2009 model years (prices found at www.carmax.com). The scatterplot below shows a strong, negative linear association between number of miles and advertised cost. The line on the plot is the regression line for predicting advertised price based on number of miles. Cost (dollars) 17998 16450 14998 13998 14599 14988 13599 14599 11998 14450 10998 18 16 o 14 12...

2. (11 pts.) Do creative people make better teachers? Ten
teachers at a large university were given a creativity test (scores
range from 0 to 20, with higher scores indicating greater
creativity) and were evaluated regarding teaching performance by
students and peers (a score of 100 indicates an average
performance, and larger scores indicate better performance). The
creativity scores and teaching performance scores are given
