Round the slope and -intercept to at least four decimal places. Regression line equation: } =|2627x + 2 6131 Alternate Answer! =16131+0.1617x Part: 1 / 3 Fait 2 of 3 If the price of eggs differs by 30.23 from one month to the next, by how much would you expect the price of milk to differ? Round your answer to at least two decimal places. The price of milk would differ by SGovernment funding: The following table presents the budget ( in millions of dollars) for selected organizations that received U.3. goverment funding for arts and culture in both 2004 and 2000 . Use a 71-94 calculator to answer the following.

Round the slope and }- Intercept to at least four decimal places. Regression line equation: ' = -4 9060 + 1 1042 x Alternate Answer: v = -4.906 + 1.1042 x Fart: 1/ 3 Part 2 of 3 If two institutions have budgets that differ by 13 million dollars in 2004 . by how much would you predict their budgets to differ in 2006 ? Round the answer to three decimal places. In 2006 , their budgets would differ by million dollars.Foot temperatures: Foot vicers are a common problem for people with diabetes. Higher skin temperatures on the foot incicate an increased risk of ulcers. In a study performed at the Colorado School of Mines, skin temperatures on both feet were measured, In degrees Fahrenheit, for & diabetic patients. The results are presented in the following table. Use a TI-84 calculator to answer the following. Left Foot Right Foot 78 86 85 75 80 80 80 Sand data to Excol Part 1 of V Compute the least-squares regression line for predicting the right foot temperature from the left foot temperature. Round the slope and J'-Intercept values to four decimal places. = 35 45907 + 57302 x Part: 1 / 4 Fart 2 of 4 Draw a scatterplot of the right foot temperature () ) versus the left foot temperature ()). Then draw the least-squares regression line on the graph.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 (miming). for a sample of 10 adults. The following table presents the results. Use a TI-34 calculator to answer the following. Systolic Diastolic Systolic Diastolic 123 77 133 91 119 1 12 118 107 71 130 76 110 74 116 70 108 69 Based on results published in the Journal of Human Hypertension Sond data to Excal Part: 0 / 4 Part 1 of 4 Compute the least-squares regression line for predicting the cisstolic pressure from the systolic pressure. Round the slope and ]'-intercept to at least four decimal places. Regression line equation:
