Need help with parts c and d.

c. Develop the regression equation for effective heating based on wattage.(Negative value should be indicated by a minus sign. Round your answers to 3 decimal places.)

d. Which heater looks like the "best buy" based on the size of the residual?(Negative value should be indicated by a minus sign. Round residual value to 2 decimal places.)

b. Conduct a test of hypothesis to determine if it is reasonable that the coefficient is greater than zero. Use the 0.10 significance level. (Negative value should be indicated by a minus sign. Round intermediate calculations and final answer to 3 decimal places.) Ho: p s 0; H1: p > 0 Reject He if t> 1.3304 Reject HO. It is quite reasonable to say the population correlation is positive c. Develop the regression equation for effective heating based on wattage. (Negative value should be indicated by a minus sign. Round your answers to 3 decimal places.)c. Develop the regression equation for effective heating based on wattage. (Negative value should be indicated by a minus sign. Round your answers to 3 decimal places.) The regression equation is: Area 0.164 Wattage d. Which heater looks like the "best buy" based on the size of the residual? (Negative value should be indicated by a minus sign. Round residual value to 2 decimal places.) The sixth heater is the "best buy." It heats an area that is square feet larger than estimated by the regression equation.A consumer buying cooperative tested the effective heating area of 20 different electric space heaters with different wattages.

Compute the correlation between the wattage and heating area. Is there a direct or an indirect relationship? (Negative value should be indicated by a minus sign. Round your answer to 3 decimal places.) The correlation of Wattage and Area is 0.904 . The link (relationship) is direct Prev 2 of 5 Next >
