Jennifer has a string attached to the end of a buoy with extra string coiled on the bottom of the tank. She measures the length
of the string from where it is attached to the buoy to the bottom of the tank as he adds more water to the tank. The length changes linearly as water is added. The table shows the collected data. What is the slope of the line that models the data?

Since Keri divides the day into different strata and each unit is selected from each strata randomly. So, it is Stratified Sampling.
Further, In Stratified Sampling population is divided into several groups such that within the group it is homogeneous and between the group it is heterogeneous. And now a selection of each stratum and unit has an equal chance of selection.
