An electrical contractor's records during the last five weeks indicate the number of job requests: Week: Requests: 21 23 21 22 23 1 23 4 5 Predict the number of requests for week 6 using each of these methods: a. Naive Number of requests23 b. A four-period your answer to 2 decimal places.) Number of requests 2225 c. Exponential smoothing with = .15. Use 21 for week 2 forecast. (Round your intermediate forecast values and final answer to 2 moving average.(Round 22.2 decimal places.) Number of Requests F3 F4 Fs F6

Explanation / Answer

a. Naive = Last period's request

= Week 5's request

=23

b. A four period's moving average = ( 23+21+22+23)/4 = 22.25

c. F3= F2 + (A2-F2)

=21 + 0.15(23-21) =21.3

F4= 21.3 + .15( 21-21.3) =21.26

F5= 21.26 + .15(22-21) = 21.41

F6= 21.41 + .15(23-21.41) =21.65
