Suppose you were given the following information from a forecasting spreadsheet, using quarterly data from the past five whole years (or 20 quarters).  You are now at the end of the fifth year.  (You’ll be using this same information on the next two questions as well.) Demand = 1000 + 14 (time) Season          Seasonal Indexes     1                        0.90            2                        1.05          3                        0.85            4                        1.20        What would be the forecast accounting for base and trend, but not seasonality, for the third quarter of the coming year (period 23)?

Using the data below, with a smoothing constant of 0.2 for the base and 0.4 for the trend, compute a trend-adjusted exponential smoothing forecast for period 2. Period     At         Ft         Tt   1          200      190       20   2

Suppose you have the following information from a forecasting software package. You have two full years of past data, and you have three periods (i.e., three terms) in each year.  You are now sitting at the end of period 6, which is the last term of the second year.  (Note:  The best-fit line equation shown below was made up by me; it may not actually be the true equation if you were to do an analysis of this data.) Demand = 40 + 10 (Time) Period     Year         Demand 1             2022            369 2             2022            460 3             2022            460 4             2023            418 5             2023            495 6             2023            590 What would be the forecast for the third term of 2024, if you didn’t care about adjusting for any seasonality?

Suppose your actual demand and your forecasts for the last 4 months looked as follows:   Month         Demand            Forecast     1                   18                    24     2                   28                    24     3                   30                    22     4                   28                    22 The four-period moving average forecast for period 5 would be 

A signal binds to a receptor and activates it.  That receptor activates another protein which activates another protein.  Which term describes this chain of activation?

Dogs are afflicted most commonly with DCM, cats are afflicted most commonly with HCM.

What protein is used to form the septum that separates two new bacterial cells?

The normal function of this class of genes is to stop replication of cells.  When mutated, these cells lead to cancer by taking away the “brakes” on cell division.

What type of signaling is used by neurons?
