Analyze the annual unemployment rates in the State of Washington before and after the recession. Provide and show in linear model graph a Scatter plot, Line of best fit (Regression line), the Slope, and VALUES OF r^2 and r

Year       Unemployment Rate

2005       5.1%

2006       4.9%

2007       4.8%

2008       6.6%

2009       10.5%

2010       9.6%

2011       8.8%

2012       7.6%

2013       6.6%

2014       5.9%

2015       5.8%

2016       5.3%

 

 

(a.)         Use the regression line to predict the unemployment rate in the state of Washington by the end of year 2017. Show work (use the equation).

 

(b.)         What is the slope of the regression line and what are the units of measurement? In a sentence,

Interpret what the slope is telling us, in the context of this real-world application.

 

 

(c.)         What is the value of the correlation coefficient, r? Also, interpret its value: Looking at the graph created and the size of r, do you judge the strength of the linear relationship to be very strong, moderately strong, somewhat weak, or very weak?
