A recent article in a college newspaper stated that college students get an average of 5.4 hrs of sleep each night. A student who was skeptical about this value decided to conduct a survey by randomly sampling 32 students. On average, the sampled students slept 5.6 hours per night. Identify which value represents the sample mean and which value represents the claimed population mean.

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
