5.2 Hypothesis Testing (Binomial Distribution)
The probability of a student in a primary school library returning his or her books on time had been found to be 0.35. Joanna, the school librarian, has started a new incentive scheme and believes that more students are now returning their books on time because of it. She conducts a hypothesis test using the null hypothesis to test her belief
3.1.1 Hypothesis Testing
A teacher carried out a hypothesis test at the 10% significance level to test if her students perform better in exams after using a new revision technique. Under the null hypothesis she calculates the probability that a value will be at least as extreme as the observed value to be 0.09142. Write a conclusion for her hypothesis test.
Hypothesis Testing
The four steps of hypothesis testing: Step 1: We state the Hypothesis. We start by assuming that the hypothesis or claim we are testing is true. This is stated in the null hypothesis. Step 2: Set the criteria for a decision. To set the criteria for a decision, we state the level of significance for a test.

Hello GPT-4o
Prior to GPT-4o, you could use Voice Mode to talk to ChatGPT with latencies of 2.8 seconds (GPT-3.5) and 5.4 seconds (GPT-4) on average. To achieve this, Voice Mode is a pipeline of three separate models: one simple model transcribes audio to text, GPT-3.5 or GPT-4 takes in text and outputs text, and a third simple model converts that text back to audio.
5.2.1 Binomial Hypothesis Testing
How is a hypothesis test carried out with the binomial distribution? The population parameter being tested will be the probability, p in a binomial distribution B(n , p); A hypothesis test is used when the assumed probability is questioned ; The null hypothesis, H 0 and alternative hypothesis, H 1 will always be given in terms of p. Make sure you clearly define p before writing the hypotheses
