Assume you collected a quarterly sales data (in millions of dollars) over a four-year period from the first quarter 2016 to the fourth quarter 2019, and computed the seasonal index for each quarter. If (actual) sales were 221 in the fourth quarter of 2018 and the (normalised) seasonal index for the fourth quarter was 0.98, what is the deseasonalised sales value (in millions of dollars) in the fourth quarter of 2018? Round your answer to two decimal places.

Assume you collected a quarterly sales data (in millions of dollars) over a four-year period from the first quarter 2016 to the fourth quarter 2019, and computed the seasonal index for each quarter. If the (normalised) seasonal index for the second quarter is 1.02, then we can interpret it as follows. a. In the second quarter, sales are 1.02% above the annual average. b. In the second quarter, sales are 2% above the annual average. c. There is a 2% difference in sales between the second quarter and the third quarter. d. There is a 1.02% difference in sales between the second quarter and the fourth quarter.

Which TWO of the following statements are FALSE?a.The analysis is false, as the seasonal effect from the month of December is largest amongst all twelve months, estimated at 103.81b. At the 5% significance level, only the seasonal components from May to October (six months inclusive) are statistically larger than that of December.c.At the 5% significance level, only the seasonal components from June to October (five months inclusive) are statistically larger than that of December.d.The seasonal effect from the month of December is included as part of the intercept in this regression model.
