A consumer buying cooperative tested the effective heating area of 20 different electric space heaters with different wattages. Here are the results. Heater Wattage Area 2,000 112 1, 250 71 1,500 187 1, 500 236 2,000 265 1,000 127 1, 500 194 2,000 186 1,000 93 2,000 236 1,500 85 1, 000 100 1, 250 208 14 1, 250 176 15 750 58 16 750 151 17 750 70 2,000 187 750 142 1, 500 163 apictureClick 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 answer to 4 decimal places.) The correlation of Wattage and Area is The relationship is b. Conduct a test of hypothesis to determine if it is reasonable that the coefficient is greater than zero. Use the 0.010 significance level. (Round intermediate calculations and final answer to 3 decimal places.) t =Ho- The data indicate that we cannot conclude that the relationship is c. Develop the regression equation for effective heating based on wattage. (Negative value should be indicated by a minus sign. Round your answers to 4 decimal places.) The regression equation is: d. What heating area corresponds with a 1,500-watt heater? (Round your answers to 4 decimal places.) Heating areae. What is the 95% confidence interval of heating the area if the wattage is 1,500? (Round your answers to 4 decimal places.)
