Answer:

a) find the attached graph

b) find the attachment no 4 and 5

c)T_{10}= 4.72+1.46(10) = 19.28

Step-by-step explanation:

a) A trend pattern exist if the time series plot gradually shifts to higher or lower values over a long period of time

find the attached graph

b) Liner Trend Equation

T_{1} =b_{0} +b_{1}t

Where T_{1} is the linear trend forecast in period t , b_{0} is the intercept of the linear trend time, b_{1} is the slope of the linear trend line, t is the time period

now computing the slope and intercept

<u>formula is attached ( 3 no attachment)</u>

Y_{t} is the value of the time series in period t, n is the number of time periods

Y(bar) is the average value and t(bar) is the average value of t

<u><em>due to unavailability of equation in math-script i attached the calculation part of this question( 4th and 5th no attachment)</em></u>

thus the linear trend equation is T_{t}= 4.72+1.46t                         (1)

T_{10}= 4.72+1.46(10) = 19.28
