Think of a project (a significant increase in average highway road in Dallas County Texas over the last 10 years) that involves data collection. Collect (a significant increase in average highway road in Dallas County Texas over the last 10 years) the needed data, propose several hypotheses and a regression model, and perform the statistical analysis required to calibrate its model or verify/refute its hypothesis.

The arrival of vehicles at a specified roadway location is Poisson distributed. The flow count shows 540 veh/hr at this roadway location. - What is the probability that headway between successive vehicles will be less than 6 seconds? - What is the probability that headway between successive vehicles will be greater than than 12 seconds? - What is the probability that headway between successive vehicles will be between 6 and 12 seconds? - Draw the probability density function of the exponential distribution and show the key items in the graph. - Draw the cumulative distribution of the exponential distribution and show the key items in the graph.
The distribution of the amount of gravel (in tons) sold by a particular construction supply company in a given week is a continuous random variable X with probability density function as shown. (a) How do you use this to find the probability that X is less than .25? (b) What about the probability that X is greater than .75? (c) What aboutP(.25 < X < .75)?
3. The amount of time that a drive-through bank teller spends on a customer is a random variable with a mean 3.2 minutes and a standard deviation of 1.6 minutes. If a random sample of 64 customers is observed, find the probability that their mean time at the teller’s window is: a. at most 2.7 minutes; b. more than 3.5 minutes; c. at least 3.5 minutes but less than 3.4 minutes.
A one way, two-lane road is shared by buses and cars. Buses travel at speed 40 mph and carry 20 people. Cars travel at speed 60 mph and carry 2 people. The fraction of vehicles that are buses passing a stationary observer is 0.2. Answer the following questions: (a) From the perspective of a stationary observer, what is the average number of passengers per vehicle? (b) What fraction of the vehicles on an aerial photograph would be buses? (c) If we take a photo of the road, what is the average number of passengers per vehicle based on this photo?
Poisson Model is used for the segment of a certain highway. Vehicles are recorded at 30-seconds intervals, the result is established that in 2251 of 20000, there are 4 vehicles arrived. Determine the number of these 20000 intervals in which, 6 automobiles arrive at the same time.
