Good evening, I need answers for the questions listed below please. If you need to use an excel sheet or a calculator, please do whatever works for you. I also write good reviews!

1.) Parts 1-3?

Carbon dioxide (C02) is produced by burning fossil fuels such as oil and natural gas, and has been connected to global warming. The following table presents the average amounts (in metric tons) of ICU;1 emissions for certain years per person in the United States and per person in the rest of the world. Use a 1184 calculator to answer the following. Year Non-U5. LLS. 1990 3.6 19.2 1991 3.6 19.0 1992 3.5 18.8 1994 3.3 19.8 1995 3.3 19.5 1996 3.4 19.? 1998 3.3 19.5 1999 3.2 19.6 2004 3.7 19.6 2005 3.3 19.5 Sail data in EEE'I (a) Compute the leastsquares regression line for predicting U.S. emissions from nonU5. emissions. Round the slope and yintercept values to four decimal places. A = Regre'SSin line equation: y {b} If me nonU.S. emissions differ by 0.2 from one year to the next, by how much would you predict the U.S. emissions to differ? Round your answer to four decimal places. The U.S. emissions would differ by [1 metric tons. (c) Predict the U.S. emissions for a year when the nonU.S. emissions level is 3.4. Round the answer to two decimal places. The U.5. emissions are predicted to be [I metic tons. Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury (IDIIJHg), for a sample of 10 adults. The following table presents the results. Use a TI84 calculator to answer the following. Systolic Diastolic Systolic Diastolic 157 103 123 77 154 94 119 69 134 87 118 88 115 83 130 76 113 77 116 70 Based on results published in the Journa! of Human Hypertension If Send data to Enoel ii Part: 0 I 4 Part 1 of 4 Compute the leastsquares regression line for predicting the diastolic pressure from the systolic pressure. Round the slope and yintercept to at least four decimal places. A Regression line equation: y = D Is it possible to interpret the yinteroept? Explain. (Choose one) '1 , the xualues are all If the systolic pressures of two patients differ by 12 millimeters, by how much 1would you predict their diastolic pressures to differ? Round the answer to three decimal places. Their diastolic pressures would differ by C] millimeters. Predict the diastolic pressure for a patient whose systolic pressure is 133 millimeters. Round the answer to one decimal place. The diastolic pressure is predicted to be D millimeters. Compute the leastsquares regression equation for the given data set. Use a TI84 calculator. Round the slope and yintercept to at least four decimal places. 7 2 IS 4 5 y 7 5 IS 2 3 H (Send data to Excel .1 A Regression line equation: y = [j Interpreting technology: A business school professor computed a leastsquares regression line for predicting the salary in 5 10005 for a graduate from the number of years of experience. The results are presented in the following Excel output. Coefcients Intercept 71.44933993 Experience 2.3957766? Write the equation of me leastsquares regression line. Use the full accuracy shown in the Exoel output (do not round your answers]. A Regression line equation: y = [:1 Predict the salary for a graduate with 6 years of experience. Round your answer to three detimal places. The salary in $1000s is D. Select the appropriate word or phrase to complete each sentence. is the estimated outcome when the value of the explanatory variable I is 0 If the leastsquares regression line has slope bl = 5, and two xvalues differ by 2, the predicted difference in the yvalues is (Choose one) 7 . If the leastsquares regression line he 2 I twe Lacvalues differ by 2, the _ predicted difference in the yualues is
