Queuing models assume that arrivals follow a Poisson process: The events (arrivals) are independent, any number of events must be possible in the interval of time, the probability of an event is proportional to the length of the interval, and the probability of more than one event is negligible if the interval is sufficiently small.

Goodwill equals the excess of the acquisition cost over the acquirer's interest in the net fair value of the identifiable assets, liabilities and contingent liabilities recognized. Consequently goodwill is US $200.000$1,000,000 - $800,000).

The correlation coefficient can vary from -1 to +1. A-1 relationship indicates a perfect inverse correlation, and a +1 relationship indicates a perfect direct correlation. A zero correlation coefficient indicates no linear association between the variables. Thus, the correlation coefficient that is nearest to zero would indicate the weakest linear association. Of the options given in the question, the correlation coefficient that is nearest to zero is
0.11.
