Question

The country is (SPAIN)

1. It is required to gather (i) the number of confirmed COVID-19 cases, (ii) cured (recovered), and (iii) deaths for each day from February 1st until May 15st *.

2. Plot three scatter graphs including conformed COVID-19 cases (?1), cured (?2), and (?3) vs week.

3. Verify that the seasonal variation for ?? ? = 1,2,3 is constant or increasing.

4. Use the natural logarithm transformation to produce a transformed series for each ?? ? =

1,2,3 that displays constant seasonal variation.

5. Use Minitab to obtain the time series model for each week (? : ? = 1, ... ,4).

6. Are dummy variables significant? Why?

7. Use Minitab to identify a point forecast and 95% prediction interval level for ?? ? = 1,2,3

8. Gather the data for the 3rd week of May and compare and contrast it with the estimated

predications (point and interval) from the previous question.

9. Make a report for the linear trend model with seasonal variation for each week (around 100

words). It should include the prediction intervals for each week in May 16th -June 15th.
