Use the Data from the Excel file titled Bears measurements to answer the following: 1. Create a scatter plot showing the relationship between the two variables: Age (x) and Weight (y) (5 pts) (Use TI - Calculator, Excel or any other software for the plot. DO NOT DRAW BY HAND). Copy and paste your plot in the space below. 2. (a) Based on the scatterplot, does a correlation appear to exist between the two variables? If so, describe the correlation (strength, direction) (2 pts) (b) Use your calculator or any software to find the correlation coefficient, r (3 pts) (c) What percentage of the variation in weight can be explained by the linear relation to the age of a bear? (3 pts) 3) Based on your analysis in step 2, do you think it is possible to infer a bear's neck from its age? Explain your answer (3 pts) 4. (a) Using your calculator or any software, find the regression equation for this data set? (4 pts) (b) Identify the slope and y = intercept of the regression equation. (3 pts) (c) What does the slope represents in this problem. (3 pts)
(d) What does the y-intercept represents in this problem. (2 pts) 5. Use your model (regression equation) to predict the weight of the bear with Age (4 pts) (a) 31 (b) 15
