Use simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series. Do not round your interim computations and round your final answers to three decimal places. For subtractive or negative numbers use a minus sign. (Example: -300) y-intercept, bo = Slope, b1 = MSE = c. What is the forecast for t = 8? If required, round your answer to three decimal places.
