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 1 1,096 235 1,509 247 1, 258 197 1. 250 118 758 222 1, 258 298 1, 096 187 1, 506 289 1,090 46 11 1, 750 118 12 1, 250 142 13 750 66 14 1, 509 242 15 1, 750 111 16 1, 508 261 17 1, 258 58 18 1,750 88 19 1,098 87 Click 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 link (relationship) is b. Conduct a test of hypothesis to determine if it is reasonable that the coefficient is greater than zero. Use the 0.025 significance level. (Round Intermediate calculations and final answer to 3 decimal places.) Ho: p s 0: H1: p > 0 Reject He if t> 2.101 1 =
