QUESTION 4 Consider the following time series data 2 3 4 10 4 Calculate a 90% prediction interval for the value of y at time period t 6 (i.e., h 2 periods ahead) Hint: You will first need to fit the model using Excel to obtain the regression output, which will give you some of the values you need for the prediction interval. Then, you will need to calculate the average and standard deviation of the values of t(use Excel). Take all calculations and the final answer to three (3) decimal places QUESTION 4 Consider the following time series data 2 3 4 10 4 Calculate a 90% prediction interval for the value of y at time period t 6 (i.e., h 2 periods ahead) Hint: You will first need to fit the model using Excel to obtain the regression output, which will give you some of the values you need for the prediction interval.
