) A probability distribution has been developed, and the probability of 2 arrivals in the next hour is 0.20. A random number interval is to be assigned to this. Which of the following would not be an appropriate interval?
A) 01-20 B) 21-40 C) 00-20 D) 41-60 E) all of the above would be appropriate
33) The logic in a simulation model is presented graphically through which of the following?
A) scatterplot B) flowchart C) blueprint D) decision tree E) None of the above
Homework Answers
1. C) 00-20
This interval would not be appropriate in this context based on the probability distribution basics
2. B) flowchart
A flowchart or flow diagram are graphical means of presenting the logic of a simulation model and it also helps in writing a simulation computer program as well.

17. A major airline company is concerned that its proportion of late arrivals has substantially increased in the past month. Historical data shows that on the average 18% of the company airplanes have arrived late. In a random sample of 1,250 airplanes, 250 airplanes have arrived late. If we are conducting a hypothesis test of a single proportion to determine if the proportion of late arrivals has increased: What is the correct statement of null and alternative hypothesis? A. H0:...

2.34. Probability integral transformation. Consider a random variable X with cumulative function Fx(x), 0-x-00, Now define a new random variable U to be a particular function of X, namely, U = Fx(X) For example, if FX(x)-1-e-Ax, then U = 1-e-Ax = g(X). Show [at least for reasonably smooth Fx(x)] that the random variable U has a constant density function on the interval O to 1 and is zero elsewhere.

Question-2 Academic Toys has developed a brand new product line—a series of Business Professor Action Figures (BPAFs) featuring likenesses of popular professors at the local business school. Management needs to decide how to market the dolls. One option is to immediately ramp up production and simultaneously launch an ad campaign in the Academic newspaper. This option would cost $1,000. Based on past experience, new action figures either take off and do well or fail miserably. Hence, the prediction is for...
