please show your calculation step by step. Quarterly data for the failures of certain aircraft engines at a local military base during the last two years are given below: Quarter 1 2 3 4 5 6 7 8 Engine Failures 200 250 175 186 225 285 305 190 Assume that both a and are equal to 0.1. In order to get the method started, we need estimates of both the intercept and the slope at time zero. Suppose that these are So-200 and Go=10. a. Apply Holt's method to obtain one-step ahead forecast values for the number of failures for periods 4 through 8. b. Forecast the demand in period 2 for period 5.

thank you
