PPT-Comparing Two Proportions

Statistics What you will learn Be able to state the null and alternative hypotheses for testing the difference between two population proportions Know how to examine your data for violations of conditions that would make inference about the difference between the two population proportions unwise or invalid. In this section we will be able to give real life examples of Fractions and Proportions. We will also learn how to solve and evaluate Fractions and Proportions in word problems.. Lesson plan goals. We are constantly using fractions everyday. Most of the time not really even noticing that we are using fractions. Have you ever checked the clock or a watch for the time? Guess what the time is a fraction of a day so any time you use a watch, clock. . Pythagoras (560-480 BC), the Greek geometer, was especially interested in the golden section, and proved that it was the basis for the proportions of the human figure. He showed that the human body is built with each part in a definite golden proportion to all the other parts.. Ratios. Comparison of two items/objects. Written one of 3 ways. As a fraction. With : (colon). . using word “to”. When writing a ratio. First thing you talk about is the numerator. Second thing you talk about is the denominator. In Unit 1, we learned the basic process of statistical inference using tests and confidence intervals. We did all this by focusing on a single proportion.. In Unit 2, we will take these ideas and extend them to comparing two groups. We will compare two proportions, two independent means, and paired data.. . 1) Learning Target: .
