 If an observed value is too many SEs away from the expected value, it is hard to explain by chance.
 ### Null Hypotheses
-A statement about a parameter, a statement of equality. The chance of getting an *x* is *y*%.
-An alternative hypothesis, or a research hypotheses, is what the researcher is out to prove. A statement of inequality (<, >, $\ne$).

 | Null Hypothesis | This is a statement about a *parameter* |
-| Alternative/Research Hypothesis |  |
+| Alternative/Research Hypothesis | What the researcher is out to prove, a statement of inequality. (Less than, greater than, not equal to). |
 | One-tailed test | Use when the alternative hypothesis says that the % of 1s is less than or greater than expected. It's one sided |

- ## c tests for averages
+| Two tailed test | When something is not equal to the expected. |

+## P Value
+The chance of observing at least a sample statistic, or something more extreme, if the null hypothesis is true.
+If the p-value is less than 5%, reject the null hypothesis.
+If the p-value is greater than 5%, fail to reject the null hypothesis.
