A company owns a production machine that cost $5,000 with a salvagevalue of zero. The machine was just sold for $1,100. Accumulateddepreciation has just been updated and accurately reflects an amountof $4,000. In good order and form record the necessary General Journalentry to dispose of the machine.

Consider a simple regression model: Y =B + BX + , i=1,..., N where e's are normally distributed with zero mean and constant variance. From a sample size of N = 20, we have = 62.9, = 65.7, (Y-Y)=261.6, (X-X) (Y-Y) = 34.8 (X-X) = 8.5 (Note: Round off the numbers in your answers to three decimal places.) a) Obtain the OLS estimates of 31 and 32 and their standard errors. b) Estimate the conditional mean value of Y when X = 5. c) Find the 99% confidence interval for the slope coefficient.
