Title: Need help thank you Post by: cristina8 on Feb 11, 2019 Researchers monitoring the number of wolves and rabbits in a wildlife reserve think that the size of the wolf population depends on the rabbit population, since wolves eat rabbits. Over the years, researchers have collected the following data.
Rabbit population - 61 72 78 76 65 54 39 43 Wolf population - 26 33 42 49 37 30 24 19 a) Generate a scatter plot for the data with the independent variable on the x- axis b) Given that the equation of the regression line is y= 0.58x-3.10, how many wolves would the regression equation predict when the number of rabbits is zero? c) Given that R2= 0.7486, calculate the correlation coefficient. Does it indicate a weak or strong relationship? d) calculate the residual values of all data points? Title: Re: Need help thank you Post by: doubleu on Feb 11, 2019 Check this solution :)
