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. . To test claims about inferences for two proportions, under specific conditions. 8.4: two-proportion inference tests. Proportions observed in independent random samples . are. independent. Thus, we can add their variances. So…. 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. Ratios. A . ratio. is a comparison of . two. numbers.. Example: Tamara has 2 dogs and 8 fish. The ratio of dogs to fish can be written in three different ways. ..  .  . ***. Be careful with the . 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. Every . A. rt. . Student . Should Know About . The Vitruvian Man . The Top Five Things . Every Art Student . Should Know About . The Vitruvian Man . Vitruvian Man. 5. The 'Vitruvian Man' is a famous drawing with accompanying notes by . 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.. two-proportion inference tests. Chapter 22. Proportions observed in independent random samples . are. independent. Thus, we can add their variances. So…. The standard deviation of the difference between two sample proportions is . Difference Between Proportions. Sometimes we want to see if there is a significant difference between independent groups.. Control group vs. treatment group or placebo group. Men vs. women.

Identify all sets to which each number belongs. . 1). . . 2). -45. 3). 3.76. 4). . 5). Simplify the following fraction: . .  . Rational number. Proportion – Learning Outcomes Express quantities as proportions of each other using fractions, decimals, ratios, and percentages. Divide quantities into a given proportion. Express errors as a proportion.
