A consumer buying cooperative tested the effective heating area of 20 different electric space heaters with different wattages. Here are the results. EsictureClick here for the Excel Data File a. Compute the correlation between the wattage and heating area. Is there a direct or an indirect relationship? (Round your answ 4 decimal places.) b. Conduct a test of hypothesis to determine if it is reasonable that the coefficient is greater than zero. Use the 0.010 significanc (Round intermediate calculations and final answer to 3 decimal places.) H0:0;H1:>0 Reject H0 if t>2.552 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. What heating area corresponds with a 1,500-watt heater? (Round your answers to 4 decimal places.) e. What is the 95% confidence interval of heating the area if the wattage is 1,500 ? (Round your answers to 4 decimal places.)
