Assume that the given x-value comes from within the range of sample data. (In other words, there will be no extrapolation.) Round your answers to 3 places after the decimal point, if necessary. (a) Suppose a sample of 23 pairs of sample data result in a test statistic ofr = 0.193 and the regression equation y = 5.5 - 7. Additionally, y = 73.1 for this data. What is the best predicted value of y for x = 10? (b)...
