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.

A space vehicle is designed to land on Mars. Assume that the ground condition on Mars is either hard or soft. If hard ground is encountered during landing, the vehicle will be successfully landed with probability 0.9, whereas, if soft ground is encountered, the corresponding probability of a successful landing is only 0.5. Based on the available information, it is judged that the chance of hitting hard ground is three times that of hitting soft ground. a. What is the probability of a successful landing? b. Suppose a stick can be projected to test the ground condition before landing. It will penetrate into soft ground with probability 0.9, and hard ground with probability of only 0.2. If the stick were observed to penetrate into the ground, what is the probability that the ground is hard? c. What is the probability of a successful landing if the stick penetrated the ground?
A researcher was observing traffic along one lane of a rural highway. During a 1 minute time interval, ten vehicles were observed travelling 65, 64, 71, 66, 58, 72, 69, 66, 55 and 62 mph. Calculate the flow rate (vph). Provide your answer to the nearest integer.
At a specified point on a highway, vehicles are known to arrive according to a Poisson process. Vehicles are counted in 20-second intervals, and vehicle counts are taken in 120 of these time intervals. It is noted that no cars arrive in 18 of these 120 intervals. Approximate the number of these 120 intervals in which exactly three cars arrive. Wrong answers will be downvoted read question carefully
QUESTION 1 A researcher was observing traffic along one lane of a rural highway. During a 1 minute time interval, ten vehicles were observed travelling 65, 64, 71, 66, 58, 72, 69, 66, 55 and 62 mph. Using these spot speeds, calculate the space mean speed (mph). Provide your answer to the nearest tenth of a mph.

I posted this question yesterday, but the solution feels wrong. In the solution, K and Kj were taken as the same value, is it correct? Apologies for resubmitting, there used to be a follow-back question option, but I can't see it.
The municipality that controls that arterial road reduced the posted speed limit, hoping to reduce the average speed of the road to 60 km/h. After introducing the new speed limit, the municipality collected a new speed sample (sample size = 220) to calculate the operating speed. The average speed and the standard deviation of the new sample were found to be 61.09 km/h and 8.95 km/h, respectively. Based on this information, answer the following question a) Is the speed reduction (if there is any) statistically significant? b) Was the target speed achieved by introducing the new speed limit?
Match the following to True/False. A. GPS devices are an example of mobile traffic sensors For the time-space diagram of a single-lane one-way road, the vehicle trajectories do not intersect with each other unless there is a crash. Pneumatic tubes detect vehicle presence by sending an electric signal to a roadside device. B. Space mean speed may be greater than time mean speed in certain situations. A. True B. False
The data shown below were obtained by time-lapse photography on a highway. Use regression analysis to fit these data to the Greenshields model and determine the following. Speed (mi/h) Density (veh/mi) 84 16.2 24.7 69 33.3 54 39.7 40 52.0 19 55.1 14 (a) the mean free speed (in mi/h) mi/h (b) the jam density (in veh/mi) veh/mi (c) the capacity (in veh/h) veh/h (d) the speed at maximum flow (in mi/h) mi/h
The accompanying data show spot speeds collected at a section of highway located in a residential area. Using the student's t test, determine whether there was a statistically significant difference in the average speeds at the 95% confidence level.

A sample of 100 over-all travel speed was observed on a four-lane, undivided Arterial Street. The sample mean was 35.45 mph, and the standard deviation of the sample was 5.20 mph. Assume that the sample of travel speeds was taken from a normal population. a) Find the percentage of vehicles in the population traveling between 33 and 44 mph. b) Between what limits may the mean of the population be expected to fall for a 95 percent level of confidence?
