Chapter 11: Chi-Square and ANOVA Tests
the Chi-Square Test for Dependence, but for historical reasons it is known as the test for independence. Just as with previous hypothesis tests, all the steps are the same except for the assumptions and the test statistic. Hypothesis Test for Chi-Square Test 1. State the null and alternative hypotheses and the level of significance

Chapter 5: Discrete Probability Distributions
coconino.eduChapter 5: Discrete Probability Distributions 158 This is a probability distribution since you have the x value and the probabilities that go with it, all of the probabilities are between zero and one, and the sum of all of the probabilities is one. You can give a probability distribution in table form (as in table #5.1.1) or as a graph.
Chapter 6: Continuous Probability Distributions
coconino.eduChapter 6: Continuous Probability Distributions 193 Section 6.3: Finding Probabilities for the Normal Distribution The Empirical Rule is just an approximation and only works for certain values. What if you want to find the probability for x values that are not integer multiples of the standard deviation? The probability is the area under the curve.
Chapter 6: Graph Theory
coconino.eduLeonhard Euler first discussed and used Euler paths and circuits in 1736. Rather than finding a minimum spanning tree that visits every vertex of a graph, an Euler path or circuit can be used to find a way to visit every edge of a graph once and only once. This would be useful for checking parking meters along the streets of a city, patrolling the
Chapter 10: Regression and Correlation
coconino.eduChapter 10: Regression and Correlation 346 The independent variable, also called the explanatory variable or predictor variable, is the x-value in the equation.The independent variable is the one that you use to predict what the other variable is. The dependent variable depends on what independent value you pick.
Chapter 9: Apportionment - Coconino Community College
coconino.eduSection 9.1 Basic Concepts of Apportionment and Hamilton’s Method . Apportionment can be thought of as dividing a group of people (or other resources) and assigning them to different places. Example 9.1.1: Why We Need Apportionment. Tom is moving to a new apartment. On moving day, four of his friends come to
