You're an investigator for the National Transportation Safety Board, examining a subway accident in which a train going at 84 km/hkm/h collided with a slower train traveling in the same direction at 20 km/hkm/h . Your job is to determine the relative speed of the collision, to help establish new crash standards. The faster train's "black box" shows that it began negatively accelerating at 1.8 m/s2m/s2 when it was 44 mm from the slower train, while the slower train continued at constant speed.

What is your report?

Delta V= ?

Solutions

Expert Solution

To avoid the crash, the train 1 has to negatively accelerate more.

A business consultant for the National Transportation Safety Board (NTSB), collected data on the safety of hybrid automobiles traveling at 30, 40 and 50 miles per hour.  She randomly assigned the same hybrid model to each condition and collected data on the pressure applied to the driver’s head during a crash into a wall at each speed. What is the independent variable? Dependent variable? Is she able to make cause and effect statements about the cars the head pressure? Explain. ...

4) The National Transportation Safety Board (NTSB) wanted to examine the safety of three different car types, as measured by head crash test percentages. Cars were classified into three groups: compact (M = , SS = ), midsized (M = , SS = ), and full-size (M = , SS = ). A one-way ANOVA was conducted and determine that there was a statistically significant (or no significant) difference between safety and type of car, F( ___, _____) = _________.

The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 77% of all fatally injured automobile drivers were intoxicated. A random sample of 51 records of automobile driver fatalities in a certain county showed that 33 involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than 77% in Kit Carson County? Use α = 0.10. (a) What is the level of significance? State the null and alternate...
