... Power of the test: 1- is the power of the test, and represents the probability of correctly rejecting a false null hypothesis. It is a measure of the ability of the test to detect an alternative mean or a significant difference when it is real Note that for a given Y and s, if 2 of the 3 quantitie ...

... Alternative hypothesis, H1 : An alternative hypothesis is a claim about a population parameter that will be true if the null hypothesis is false. Test Statistic : is a function of the sample data on which the decision is to be based. p-value: is the probability calculated using the test statistic. T ...

... Computing Measures of the Most Likely Event We will NOT include computations for the mode because there are none. You just identify the group with the highest frequency, There are two types of equations for each measure: 1) Parametric measure. This is the real value or parameter of the population. 2 ...
