(11 points) It's a dog's lifeThe ite expectancy of a dog wies depending on the breed and size of the animal Dance was to investigate this relationship for data project this semester. Using Information from Wikipedia Dasele comptes a f 48 breed of dogs and record the average weigh in pounds Weight and the site expectancy in years. Years for each breed The scatter pilok and a summary of Daniele data la over below. The correlation between Weight and Years was found to be a 07546 Round it calculated answers to 4 decimal places Lite Expectancy by Average Weight Life expectancy in years (Years) BO 20 Weight in pounds (Weight) Variables Weight Year's Mean 22624 12.1035 Sample 50 156335 20412 1. The relationship between Weight and Years is best described as and ?? 2. Collate the slope and interest for the near regression equation that predicts Years from Weight Note: Do not use rounded values for intermediate calculations! Slope and intercept Yo wish The

3. Fil in the blank The value for Daniel's near regression model of Years from weight is The meant of the variation 777 can be explained by its finear relationship 222 4. As part of her analysis. Daniele examines the residuals for her regression model to detine coon for inear regression have been met which condition is Danielle checking with the following prot? Residuals vs. Fitted Values . . 12 12 14 10 11 Filed Values O A Danietis checking to see if the variability of points around the least squares inestoughly constant OB Danielleis cheer the strength of the evidence that the slope of the regressonline is nonzero OC Daniele is checking to see if the slope of the regression equation is positive or negative. OD Daniele is checking to see if the residuals are nearly normal 5. After Danielle presents her project in class her classmate Omar wants to use the results for his famay dog's breed, which was not one of the breeds in Danede dataset. He finds the average weight of his dog's breed to be 98.1 pounds is appropriate for Onarto e Danielle regression equation to estimate the fe expectancy of his dog? 77? because OA Regression equations can only be used to calculate confidence as for the slope. OB Daniel's model is only valid for the 46 dog breeds she used to create the model The value for weight for Omar's dog breed is within the range of the data Daniele used to create the model D. The value for weight for Onars dog breed is not within the range of the data Daniele in create the model . 9:24 AM 4/26/2002
