First, a hypothesis statement and assumption are made about the population parameter or probability distribution. This initial statement is called the Null Hypothesis and is denoted by Ho.

Step 1: Based on the null and alternative hypotheses and given alpha, find a critical z-value (or z-values). Remember that alpha is the tail probability (in the right tail for the given alternative ...

You are now ready to perform statistical analysis of your results, but first, you have to choose a critical value at which to reject your null hypothesis. You opt for a critical value probability ...

The probability that the null hypothesis will be rejected when it is actually true is called the false positive rate and is determined by the significance level of the test (called alpha which is ...

It tests the null hypothesis that the distribution of the response variable does not differ among classes. It is designed to detect alternatives of ordered class differences, which can be expressed as ...

The power of a test is the probability of rejecting the null hypothesis when the alternative is true. In this case, the power is the probability of accepting equivalence when the treatments are in ...

Successful completion of this course demonstrate your achievement of the following learning outcomes for the MS-DS program: Define a composite hypothesis and the level of significance for a test with ...
