Although the two lines areexactly the same length, the vertical line appearsto be much longer. To examine the strength of thisillusion, a researcher prepared an example in whichboth lines were exactly 10 inches long. The examplewas shown to individual participants who were toldthat the horizontal line was 10 inches long and thenwere asked to estimate the length of the vertical line.For a sample of n =estimate was MCS25 participants, the average12.2 inches with a standarddeviation of s = 1.00.K.edorntedteAn example of the vertical-horizontal illusiona.

. Interpret your result from part (a) if the assumptions for regression inferences hold. Choose the correct interpretation below. A. Presuming that the variables age and price for Corvettes satisfy the assumptions for regression inferences, the standard error of the estimate provides an estimate for the common population standard deviation, σ, of ages for all Corvettes of any particular price. B. Presuming that the variables age and price for Corvettes satisfy the assumptions for regression inferences, the standard error of the estimate provides an estimate for the slope, β1, of the population regression equation for ages for all Corvettes of any particular price.
