Question

Linear trend is calculated as Tt = 28.5 + 0.75t. The trend projection for period 15 is

a. 11.25
b. 28.50
c. 39.75
d. 44.25

Answer 1

The trend projection for period 15 using the given linear trend equation Tt = 28.5 + 0.75t is c. 39.75.

Step-by-step explanation:

The linear trend equation given is Tt = 28.5 + 0.75t, where t represents the time period. To find the trend projection for period 15, we substitute t with 15 into the equation:

T15 = 28.5 + 0.75(15)

Now performing the calculation:

T15 = 28.5 + 11.25 = 39.75

Therefore, the trend projection for period 15 is 39.75, which corresponds to option c.
