Answer:
See below
Step-by-step explanation:
This is a decreasing exponential function so the curve will decrease from the x = negative infinity ( negative x and positive y area) and continue to approach the x axis at positive infinity but will never reach 0 . The x axis is an asymptote to the curve. It will cross the y axis at y = 5.
Which sampling method divides the population up into sections, randomly selects some of those sections, then chooses all the members from the selected sections to study?
What is Cluster Sampling?
Cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research. Researchers then select random groups with a simple random or systematic random sampling technique for data collection and data analysis.
So, The above mentioned type of sampling is called cluster sampling.
Cluster sampling is a sampling technique in which the entire population of interest is divide into clusters or groups, then the investigator randomly selects some of these clusters and all the members of these randomly selected clusters are investigated.
