You may use a calculator and roughly sketch on paper. Describe the relationship between the two variables (strength and direction). c) Find the linear correlation coefcient (use a calculator) d) State the hypotheses in symbols and words. e) is there a statistically signicant linear relationship between x and y? Explain. You can use the pv:i|ue or the critical values in Table A-6. f) Calculate the least squares line if appropriate. Put the equation in the form of: y-hat a+bx is there a statistically signicant linear relationship between x and y? Explain. You ran use the p-value or the critical values in Table A-6. f) Calculate the least squares line if appropriate. Put the equation in the form of: y-hat = a + bx 3) What is the slope? interpret the slope. h) Predict the blood pressure of a 47-year-old man, assuming there is a linear relationship. i) Predict the blood pressure of a 48- year old man, assuming there is no linear relationship.
