How can we use samples to make inferences about a population?AIM:Announcements: The NYS Math Assessment will take place Tuesday, May 2 to Thursday, May 4.Inferences from samples worksheet (found below)HW: Do Now:The question you are investigating is: Do young people these days use their phones too much? How might you go about surveying a random sample? Classwork:Yesterday's work with random samples flows into today's lesson on inferences from random samples. We will be using the results from random samples to make predictions about a population. This concept is extremely important during election times when sample polls are used to make predictions about potential candidate victories. We conducted an experiment in class to simulate this idea using a paper bag and colored tiles. Each bag had 25 tiles, some red and some different colors. Students were not allowed to look into the bag. They took a sample of 5 and counted how many of the 5 were red. They used this amount to predict how many were red in the bag and then compared their predictions to the actual amount. :Resourceshttps://www.khanacademy.org/math/cc-seventh-grade-math/cc-7th-probability-statistics/cc-7th-population-sampling/e/making-inferences-from-random-samples
