Estimation and Confidence Intervals

Learners turn sampling distributions into estimates with honest uncertainty. They build confidence intervals for a proportion after checking conditions, interpret intervals and confidence levels correctly, see how confidence level and sample size change the margin of error, choose a sample size for a desired margin, and construct a t interval for a mean.

  • 4 lessons
  • About 145 minutes
  • Confidence intervals check: 11 questions
  • Ways to answer: choose an answer, highlight a text, type a number, put in order, true or false and write a short answer
