A contractor's records during the least five weeks indicate the number of job requests: Week Request 1 24 2 23 3 22 4 21 5 18 Predict the number of requests for week 4, weck 5, week 6 using each of the following methods: 1) Naive approach 2) 2-period moving average 3) 4-period moving average 4) Weighted moving average using 0.50, 0.40 and 0.10 assuming highest weight to the most recent week 5) Exponential smoothing with a = 0.20; use 24 for week 3 forecast. Paul is conducting an experiment to relate fuel economy (MPG) with the amount of CO2 (grams/mile) Paul conducted an experiment on 12 different vehicle owners. Table below presents the fuel economy and CO2 emitted Fuel economy Vs. CO2 emissions. Fuel Economy (MPG) CO, emissions(g/mi) 29.2 304 25.3 324 27.5 312 28.1 317 28 316 23.1 344 26.1 342 25 356 23.4 381 21.7 389 22.2 399 1) Obtain a linear regression equation line for the data 2) Predict the CO2 emissions when the fuel economy is 24 MPG
