please answer all parts for thumbs up. one question with many parts. thank you. Chapter 10: Round all numbers to two digits after the decimal point. (30pts.) Use the Data from the Excel file (Chapter 10): Bears (measurements from anesthetized wild bears) to: 1. Create a scatter plot showing the relationship between the two variables: Age (x) and Neck (y) 2. Write up an analysis of all the information that you learn from the graph a) State the correlation coefficient. Is there a significant correlation between the variable age and neck of a bear? (Why? Compare r with the critical r value, Use significance level 0.05.). b) If there appear to be a correlation, describe the correlation (direction, strength). c) What percentage of the variation in neck can be explained by the linear relation to the age of a bear? 3. Answer all of the following questions a) 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. b) What is the regression equation? c) Using the relationships from part b, determine the approximate age of a bear with the following neck: - 23 inches 7 inches S Is the second calculation meaningful? Why? d) Suppose you predict that the weight of the neck is 25inches, and you latter find out that the neck of that bear is actually only 18 inches. Give one possible reason that your prediction was incorrect. e) Using the relationships that you calculated, determine the approximate neck of a bear with age 56 4. Using the relationship between the age and the neck answer - age 101 the following questions: a) What does the slope of the regression equation represent? b) What does the y-intercept represent? Is it meaningful? Solution here consider different ages, now, perabola curve used now, this method useful find out easy solution, . ..
