The result of the significance test consistent with the notion that buyers pay attention to a surcharge when it is levied by a low-reputation seller. The mean square due to error (MSE) is an unbiased estimator of the variance of the error variable e in the regression model. In this regression analysis, the MSE equals , and the standard error of estimate equals 64.3560 89 The sample variance of shipping costs for the auctions in the sample is 3.39. 32.0562 46.0532 A different sample of eBay auctions cannot be expected to provide the same value of by as the current sample. So bi is a random variable. Its sampling distribution has an estimated standard deviation of The 90% confidence interval estimate of B, is to Since O is in the confidence interval, you infer that there is a significant Tinear relationship between shipping cost and winning bid. This result consistent with the notion that buyers pay attention to a surcharge when it is levied by a low-reputation seller. Use the Distributions tool to help you answer the questions that follow.
