An olympic swimmer competes in the same events during each long course swim season. a swimmer currently competing on the united states women’s olympic swim team, will swim her best events each year with the hope of continuous improvement. the following table is a record of the swimmer’s best times for the 100 meter freestyle event, measured in long course meters. long course season recorded best time 2005 2: 33.42 2006 2: 24.81 2007 2: 10.93 2008 2: 03.45 2009 1: 58.67 2010 1: 59.17 2011 1: 55.06 2012 1: 55.82 2013 1: 54.81 2014 2: 00.03 2. use the scatter plot to determine whether there is positive, negative or no correlation between the data values. 3. write a conclusion statement regarding the data and the rate of change present in the line of best fit. do not actually calculate the slope or write the equation for the line of best fit.
