a.

Summary Introduction

To calculate:The one-step forecasts for February through May with the use of exponential smoothing.

Introduction:Exponential smoothing of time series involves assigning datain exponentially decreasing weights fromlatest to oldest observations. Simply by putting the older data, less priority is given to the data. The newer data becomes more relevant to which more weight is assigned.

b.

Summary Introduction

To calculate:The difference in forecasts if value of α is 0.40.

Introduction: Exponential smoothing of time series involves assigning datain exponentially decreasing weights from latest to oldest observations. Simply by putting the older data, less priority is given to the data. The newer data becomes more relevant to which more weight is assigned.

c.

Summary Introduction

To calculate: The MSEs for the forecasts obtained in parts ( a ) and ( b ) for February through April and to find out the more accurate forecasts for the value of α , based on the MSE.

Introduction: Exponential smoothing of time series involves assigning datain exponentially decreasing weights from latest to oldest observations. Simply by putting the older data, less priority is given to the data. The newer data becomes more relevant to which more weight is assigned.

A company operates a manufacturing plant that produces two products, A and B. The plant has the following capacity data: Design Capacity: 15,000 machine hours per month Effective Capacity: 12,000 machine hours per month Actual Output (Utilized Capacity): 10,000 machine hours per month Additionally, the plant produces Product A and Product B, with the following production data: Product          Demand (Units)       Processing Time (hours per unit)                  Contribution Margin ($ per unit)   A                      3,000                                2.5                                                                   40     B                  4,000                                 1.5                                                                     30 Calculate the plant’si.Capacity Utilization ii.

Major League Baseball's World Series is a maximum of seven games, with the winner being the first team to win four games. Assume that the Atlanta Braves and the Minnesota Twins are playing in the World Series and that the first two games are to be played in Atlanta, the next three games at the Twins' ballpark, and the last two games, if necessary, back in Atlanta. Taking into account the projected starting pitchers for each game and the home field advantage, suppose the probabilities of Atlanta winning each game are as follows. Game 1 2 3 4 5 6 7 Probability of Win 0.61 0.56 0.47 0.44 0.47 0.54 0.49 Construct a simulation model in which whether Atlanta wins or loses each game is a random variable. Use the model to answer the following questions. (Use at least 1,000 trials.) (a) What is the average number of games played regardless of winner? (Round your answer to one decimal place.) games (b) What is the probability that the Atlanta Braves win the World Series? (Round your answer to…
