Presentation transcript:

Shaquille O'Neal has made 53 Shaquille O'Neal has made 53.3% of his free throws over his career, during this past offseason he worked with a free throw coach and then started out the next season making 26 of 39 free throws. Is this evidence that Shaq has significantly improved his free throw shooting ability? Describe a Type I and Type II error in this situation.

Accept or reject? We understand with normal variation and everything working normally, we will get a sodium value between 1.9723 mg and 2.0277 mg 95% of the time.

Accept or reject? We understand with normal variation and everything working normally, we will get a sodium value between 1.9723 mg and 2.0277 mg 95% of the time. This means the 5% of the time you will reject a batch of chips that are fine. When we reject the batch (and H0) incorrectly we have committed a Type I error.
