1. Using the table below as your reference, can you easily predict the number of job gains in 2020 based on the years before? If yes, explain what method(s) you would
use to predict the job gains in quarter 4 (Q4) for the year 2020. If no, explain what
would make it difficult for you to predict job gains for Q4 in 2020. The table
includes job gains reported in Q4 and they are reported in the thousands. (Note:
multiply each number by 1000 to see the actual amount of job gains; reported in
smaller numbers to actually make graphs and tables easier to read).
