In this project, we'll use our unique IAT random samples to demonstrate what we learned in Unit 4 (Module 11).
WARNING: Since this project is equivalent to an exam, I will not be able to help you. However, you can still rely on your classmates for help, and I can answer clarification questions.
Progress Check
Use this activity to assess whether you can:
Describe the sampling distribution for sample proportions and use it to identify unusual (and more common) sample results.
Distinguish between a sample statistic and a population parameter.
Use StatCruch to find a confidence interval to estimate a population proportion when conditions are met.
- Interpret the confidence interval in context.
- Interpret the meaning of a confidence level and relate it to the margin of error when testing a claim.
- Given a claim about a population, determine the null and alternative hypotheses.
- Conduct a hypothesis test for a population proportion and state a conclusion in context.
- Interpret the P-value as a conditional probability.
- Recognize type I and type II errors and articulate the consequence of either error.
- Directions
- WARNING: The directions for Unit Projects differ from the directions for homework and lab assignments.
