TABLE 16-12
A local store developed a multiplicative time-series model to forecast its revenues in future quarters,using quarterly data on its revenues during the 5-year period from 2008 to 2012.The following is the resulting regression equation:
log10
= 6.102 + 0.012 X - 0.129 Q1 - 0.054 Q2 + 0.098 Q3
where is the estimated number of contracts in a quarter
X is the coded quarterly value with X = 0 in the first quarter of 2008
Q1 is a dummy variable equal to 1 in the first quarter of a year and 0 otherwise
Q2 is a dummy variable equal to 1 in the second quarter of a year and 0 otherwise is a dummy variable equal to 1 in the third quarter of a year and 0 otherwise
-Referring to Table 16-12,to obtain a forecast for the third quarter of 2013 using the model,which of the following sets of values should be used in the regression equation?
P-Value
The probability of observing test results at least as extreme as the results actually observed, assuming that the null hypothesis is true.
West Nile Virus
A virus transmitted to humans and animals through the bite of an infected mosquito, known for causing West Nile fever.
Null Hypothesis
A hypothesis that there is no effect or no difference, and it serves as a default hypothesis in statistical hypothesis testing.
Alternative Hypothesis
A statement that suggests there is a statistically significant difference between two or more data sets, contrary to the null hypothesis.
