A biologist looked at the relationship between number of seeds a plant produces and the percent of those seeds that sprout. The results of the survey are shown below.

1.  r2 = ?  (Round to 3decimal places)


2.  Interpret r2 :
   
   
   

   
   
   • Given any group of plants that all produce the same number of seeds, 57% of all of these plants will produce seeds with the same chance of sprouting.
   
   
   • 57% of all plants produce seeds whose chance of sprouting is the average chance of sprouting.
   
   
   • There is a 57% chance that the regression line will be a good predictor for the percent of seeds that sprout based on the number of seeds produced.
   
   
   • There is a large variation in the percent of seeds that sprout, but if you only look at plants that produce a fixed number of seeds, this variation on average is reduced by 57%.

   The equation of the linear regression line is:
   ˆy^ = ? +? x  (Please show your answers to 3 decimal places)
