How can we disprove a claim without perfect evidence?
Learning objectives, requirement tasks, and mastery assessments  Setup a hypothesis test of a population parameter, run the test using simulation, make a logical conclusion, and be aware of potential errors.
 Task:
 In class simulations of disproving a claim and analyzing the cost/benefit of errors
 Create video scenes for video:
 Generate a question about BHS students (what percent do ___) and ask a teacher to state their claim.
 Create an alternative hypothesis.
 Complete a SRS of 30 students to obtain evidence for the true answer to the question.
 Calculate a pvalue for the scenario.
 Mastery quiz:
 Understand the purpose of a hypothesis test
 Understand the logic of a hypothesis test
 Properly write null and alternative hypotheses.
 Use random simulation to estimate a pvalue for proportions
 Understand the difference between statistical and practical significance.
 Understand how to choose a level of significance, α, and when you should reject the null.
 Understand Type I and Type II errors and how their probabilities are labeled.
 Mastery freeresponse questions:
 How to generate/find a null hypothesis
 3 ways to better reject the null
 Connection between confidence intervals and hypothesis tests
 Use confidence intervals, the normal curve, and computational methods to more broadly understand the meaning of a pvalue.
 Task:
 Summary and calculations for video:
 Calculate a pvalue with the normal curve, checking assumptions first.
 Write an accurate sentence clearly describing your pvalue.
 Write a conclusion statement about your result.
 Mastery quiz:
 Use prior knowledge of hypothesis testing.
 Checking assumptions for use of the normal curve.
 Calculate and sketch a pvalue using the normal curve and zscore
 Write an accurate sentence clearly describing your pvalue.
 Conclude about statistical significance and rejection.
 Mastery freeresponse topics:
 Bootstrap vs. math model for calculation
 Pvalue in a sentence
 Perform 2sided test with a confidence interval
 In a team, use a video to demonstrate the complete process of obtaining a claim, selecting an alternative, gathering evidence, analyzing the data, and making an informed conclusion.
 Task:
 Compile the video work from the previous sections, along with a creative storyline, into a short demonstration of the hypothesis testing process.
 Mastery freeresponse questions:
 Compare and contrast the purpose of a confidence interval, as used in the infographic, with a hypothesis test, as used in the video.
 Why did the simulation and normal curve approaches to finding a pvalue differ? Why does or does this not bother you?
 How did you take a leadership or captain role on an even number of tasks during the project?
 Did the video help you improve your understanding of how to do hypothesis tests? How could we setup the project differently to improve it next semester?
