A group of students are designing a field study to investigate the length of time a traffic light remains yellow. In the interests of safety, one of the students suggested the following rules:
• Study the traffic lights at intersections where the speed limit is 70 km/h or less.
• Avoid rush hour. Study traffic lights outside of times when people are going to and from work and school.
Indicate how each of these rules may limit the useful data that comes out of the investigation.

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
