A biologist is studying the plant diversity in 15 million acres of the Sierra Nevada Mountains. He will count the number of species in 150 acres. Match the strategies to their corresponding sampling techniques. The biologist goes to 15 diverse locations that have 10 acres each and surveys all 10 acres for each of these 15 locations. The biologist goes to his 150 favorite hiking places and looks at an acres along each trail. The biologist classifies the Sierras into 10 different ecological types and then makes sure that the proportion of each ecological type from the sample is the same as the proportion of that of the population. The biologist enters the 15 million acres into a data base and had a computer randomly select 150 of these acres. The biologist orders the 15 million acres by latitude and then surveys every 100000th acre on the list.

A researcher studying allergies to animals is interested in performing a study at the local elementary school. At Pineview Elementary, there are 4 1st grade classrooms. The researcher picks 2 of the 4 classrooms and asks every 1st grader in the 2 classrooms what type of animal they own (cat, dog, rabbit, etc.). He also asks how often they experience allergies. What is the sample?
As part of a sixth-grade class project the teacher brings to class a large jar containing 200 gumballs of two different colors: red and green. Andy is asked to draw a sample of his own choosing and estimate the number of red gumballs in the jar. Andy draws a sample of 25 gumballs, of which 15 are red and the rest are green. Use Andy's sample to estimate the number of red gumballs in the jar. Answer:
