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?
The figure shows a top view of an intersection where a traffic accident occurred. Vehicle 1 was traveling eastward while Vehicle 2, traveling northward, ran through a stop sign and crashed into Vehicle 1. The collision was violent. As the vehicles crushed, they became entangled and moved as one, sliding across the intersection and leaving the road. Here are some technical details of the accident: • Vehicle 2 was larger, weighing 50% more than Vehicle 1. • According to a driver following Vehicle 1, it was traveling at the posted speed limit. • Both streets had the same speed limit. It is not known how fast Vehicle 2 was traveling. • The collision caused Vehicle 1 to divert its path by an angle of 0 = 60°, as shown in the figure. • The street was covered with snow and ice, making conditions very slippery. Use the information above to answer the following questions. (I'm expecting the first question to be fairly straightforward, and the second question to be more tricky.) 1. We know that…

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?
