Answer the 5th question plus 1 more from questions 1–4. Then reply to 1 classmate’s thread.

  1. The table below shows the demand for gadgets (they’re like widgets, only they’re more mechanical) over a 5-month period. Calculate exponential smoothing forecasts for each month and for July. Use a coefficient of 0.5 and assume that the forecast for January was 8. Also, evaluate the quality of the exponential smoothing model by calculating the root-mean-square error for the data set. Note: Round all intermediate calculations to 2 decimal places (see table at bottom).
  2. Evaluate the performance of using the composite index of leading indicators in forecasting the recession in the U.S. (you may need to search additional information for answering this question).

  • “Alcohol Facts: Alcohol is created when grains, fruits, or vegetables are fermented, a process that uses yeast or bacteria to change the sugars in the food into alcohol. Alcohol has different forms and can be used as a cleaner or antiseptic; however the kind of alcohol that people drink is ethanol, which is a sedative. When alcohol is consumed, it’s absorbed into a person’s bloodstream. From there, it affects the central nervous system (the brain and spinal cord), which controls virtually all body functions. Alcohol actually blocks some of the messages trying to get to the brain. This alters a person’s perceptions, emotions, movement, vision, and hearing” (
