      Week 1

      Preparatory assignment 1.0

      Theory

      1. What symbols are used for the population mean and the sample mean?

      2. What is the difference between the H0 and the Ha?

      3. What is the definition of a p-value?

      4. What is the definition of the rejection criterion α?

      Application

      Select the correct response(s). (More than one may be correct.) The p-value for testing H0 : µ = 100 against Ha : µ is not 100 is p = .001. This indicates that:

      1. There is strong evidence that µ = 100.

      2. There is strong evidence that µ is not 100.

      3. There is strong evidence that µ > 100.

      1. There is strong evidence that µ < 100.

      2. If µ were equal to 100, it would be unusual to obtain data such as those observed.

      Workgroup tips

      It is important that you understand the difference between a sample and a population, and that you understand the difference between the symbols for them. A sample is the one test result set that a research or investigation delivers, or one group of people from one specific experiment, while a population is an overview of anybody who fits to the requirements. Below is a table of different symbols for the two different situations.
