Consider the following time series. (a) Choose the correct time series plot. (i) What type of pattern exists in the data? (b) Use simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series. If required, round your answers to two decimal places. Use a minus sign for negative numbers, if any. y-intercept, b0= Slope, b1= MSE= (c) What is the forecast for t=8 ? If required, round your answer to one decimal place
