Hypothesis Test | pertaining to one population for testing a claim about some parameter of the population. |
Null Hypothesis | a statement that the value of a population parameteris equal to some value. |
Alternative Hypothesis | a statement that the population parameter has a value that somehow differs from the value in the null hypothesis. |
Test Statistic | a value that is computed from a sample data. |
Traditional Method | invloves critical values and critical regions. |
P-value Method | involves the calculation of a P-value. |
Critical Region | a set of values of the test statistic that causes us to reject the null hypothesis. |
Significance Level | the probability that the test statistic will fall in the critical region when the null hypothesis is actually true. |
Critical Value | the value that separates the critical region from the non-critical region. |
Two-Tailed | if the sign is H1is not = to. |
Right-Tailed | if the sign is H1>. |
Left-Tailed | if the sign is H1<. |
P-Value | the probability of getting a value of the test statistic that is at least as extreme as the one representing the sample data, assuming the null hypothesis is true. |
Type I Error | if the null hypothesis is true, but we reject it. |
Type II Error | if the null hypothesis is false, but we fail to reject it. |
