Is there a direct or an indirect relationship? Note: Round your answer to 4 decimal places. Conduct a test of hypothesis to determine if it is reasonable that the coefficient is greater than zero. Use the 0.010 significance level. Note: Round intermediate calculations and final answer to 4 decimal places. Develop the regression equation for effective heating based on wattage. Note: Negative value should be indicated by a minus sign. Round your answers to 4 decimal places. What heating area corresponds with a 1,500-watt heater? Note: Round your answers to 4 decimal places. What is the 95% confidence interval of heating the area if the wattage is 1,500? Note: Round your answers to 4 decimal places.
