- IntroductionIntroduction to traditional hypothesis testing
- 1.Traditional Proportion Hypothesis Testing
I make the claim that "75% of people like statistics." If 50 people were sampled and it was found that 64% of them like statistics then with a significance level of α=0.05 can my claim be proven to be false? - 2.Thomas is shopping for a used car. He is fairly unconcerned with what car he buys and makes the claim that "[he] likes most cars". If he checks out 40 cars and he likes 30 of them, with a 90% confidence level is his claim true?
- 3.Traditional Mean Hypothesis Testing
Daisy is brewing a batch of Kombucha. She made a total of 20 jars, with a standard deviation of σ=2 oz. If she samples 5 jars and finds that the mean amount of liquid in these 5 jars is x=27 oz, then with 99% confidence what could be said about the claim that "she has on average less than 30 ounces per jar".
