• Chapter 6 – Hypothesis Testing: Continuous Variables

When students have completed this lesson they should be able to:

• Understand the nature of a hypothesis test
• Understand the difference between a one-tail and a two-tail test
• Formulate a null hypothesis and an alternative hypothesis
• Understand the terms ‘significance level’ , ‘rejection region’ , ‘acceptance region’ and ‘test statistic’
• Carry out a hypothesis test of a population mean for a sample drawn from a normal distribution of know variance, and also for a large sample

Chapter 7 – Hypothesis Testing: Discrete Variables

When students have completed this lesson they should be able to:

• Formulate hypothesis and carry out a test of a population proportion by direct evaluation of binomial probabilities or by a normal approximation, as appropriate
• Formulate hypothesis and carry out a test of a population mean using a single observation drawn from a Poisson distribution, using either direct evaluation of probabilities or by normal approximation, as appropriate

Chapter 8 – Errors in Hypothesis Testing

When students have completed this lesson they should be able to:

• Know what Type I and Type II errors are
• Calculate probabilities of Type I and Type II errors in the context of the normal, binomial, and Poisson distributions
