Question

39. TABLE 16-5

A contractor developed a multiplicative time-series model toforecast the number of contracts in future quarters, usingquarterly data on number of contracts during the 3-year period from1996 to 1998. The following is the resulting regressionequation:

ln Y = 3.37 + 0.117 X - 0.083 Q1+ 1.28 Q2 + 0.617Q3

where Y is the estimated number of contracts in a quarter
X is the coded quarterly value with X = 0 in the firstquarter of 1996.
Q1 is a dummy variable equal to 1 in the firstquarter of a year and 0 otherwise.
Q2 is a dummy variable equal to 1 in the secondquarter of a year and 0 otherwise.
Q3 is a dummy variable equal to 1 in the thirdquarter of a year and 0 otherwise.


Referring to Table 16-5, using the regression equation, which ofthe following values is the best forecast for the number ofcontracts in the third quarter of 1999? A)252
B)277
C)228
D)311
40. Blossom's Flowers purchases roses for sale for Valentine'sDay. The roses are purchased for $10 a dozen and are sold for $20 adozen. Any roses not sold on Valentine's Day can be sold for $5 perdozen. The owner will purchase 1 of 3 amounts of roses forValentine's Day: 100, 200, or 400 dozen roses. Given 0.2, 0.4, and0.4 are the probabilities for the sale of 100, 200, or 400 dozenroses, respectively, then the EMV for buying 200 dozenroses is A)$4,500
B)$1,700
C)$1,000
D)$2,500
41. Maintaining the gains that have been made with a revisedprocess in the long term by avoiding potential problems that canoccur when a process is changed involves which part of the DMAICprocess? A)Define
B)Measure
C)Analyze
D)Improve
E)Control
