Analyzing Survey Data and Proportions

Mrs. Maha's video lesson for Math 7 covers making inferences from random samples. The lesson includes several examples: estimating the number of students preferring fall at Franklin High School, athletes favoring hockey at Gammon Middle School, clients planning vacations at Getaway Travel Agency, citizens preferring rock music in Thrown County, and mothers with fewer than two kids in the Mothers Club. Each example involves setting up a proportion based on a random sample and solving it to estimate the population's preference.
