Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.

Question

Drop-off points (points de collecte in French), where residents can dispose of their organic waste
for composting, were established in each of the five targeted neighborhoods of PROBLEM 1.
Camille wants to see whether or not there exists a relationship between the average weekly amount
of non-disposed food waste per household and the availability of drop-off points in the
neighborhood, expressed as the number of households per drop-off point (considered fixed). Her
data and some of her preliminary calculations are presented below:

2) Camille also calculated the slope of the fitted regression line: estimated slope = 0.008. Test
whether or not the availability of drop-off points in the neighborhood has a linear effect on the
amount of non-disposed food waste per household. Use a =
: 0.10.
