LESSON 16: ESTIMATING POPULATION PROPORTIONS

Let’s estimate population proportions using samples.

I can...

• estimate the proportion of population data that are in a certain category based on a sample.

Standard: 7.NS.2., 7.RP.A, 7.SP.2&4

1) Math Ready and Do Now

2) Core Problems:

Spiral Vocab: In statistics, a proportion is a number between 0 and 1 that represents the fraction of the data that fits into the desired category. For example, with the data: {Yes, Yes, Yes, No, Maybe} the proportion of “Yes” answers is 3/5, 0.6, or 60%
