The speeds of vehicles on a highway with speed limit 90 km/h are normally distributed with mean 101 km/h and standard deviation 6 km/h. (Round your answers to two decimal places.)

(a) What is the probability that a randomly chosen vehicle is traveling at a legal speed?

(b) If police are instructed to ticket motorists driving 115 km/h or more, what percentage of motorist are targeted?

Thank you in advance! The District of Columbia Police Department are gathering highway speed data along a section of the Capital Beltway to determine if the current speed limit is being followed. A radar speed detection device is used to measure the speeds of cars on the expressway. The speeds are normally distributed. The speed gun captures the speed of 6 vehicles as 80mph, 70mph, 100mph, 70mph, 80mph and 80mph. What is the mean of the speeds on the expressway...

A construction zone on a highway has a posted speed limit of 40 miles per hour. The speeds of vehicles passing through this construction zone are normally distributed with a mean of 45 miles per hour and a standard deviation of 5.6 miles per hour. Find the percentage of vehicles passing through this construction zone that are exceeding the posted speed limit. Round to four decimal places.

The existing posted speed limit on a section of highway is 88 km/h and studies have shown that the current 85th percentile speed is 104 km/h. If the posted speed limit is to be increased to the current 85th percentile speed, what should be the increase in the radius of a curve that is just adequate for the existing posted speed limit? Assume a superelevation rate of 0.08 for the existing curve and for the redesigned curve.

A car is travelling on a straight highway where the speed limit is 110 km/h. You are watching it from a point 10 meters away from the road, and at the instance when the car is 20 meters directly away from you the angle that your line of sight makes with a perpendicular to the road increases at the rate of 3 4 radians/sec. Is the car breaking the speed limit? Fully justify your answer. (Note that 1 m/s =...

Traffic police monitor the speed of vehicles as they travel over a new bridge. The average speed for a sample of 4141 vehicles was 81.3581.35 km/h, with the sample standard deviation being 4.524.52km/h. We will assume that the speeds are Normally distributed, and the police are interested in the mean speed. Part a) Since the variance of the underlying Normal distribution is not known, inference here would involve the t distribution. How many degrees of freedom would the relevant t...

A state highway goes through a small town where the posted speed limit drops down to 40MPH, but which out of town drivers don’t observe very carefully. Based on historical data, it is known that passenger car speeds going through the city are normally distributed with a mean of 47 mph and a standard deviation of 4MPH. Truck speeds are found to be normally distributed with a mean of 45MPH and a standard deviation of 6MPH. The town installed a...
