Students and teachers at a school were polled to see if they were in favor of extending the parking lot into part of the athletic fields. The results of the poll are shown in the two-way table below. Which of the following statements is false? The table below shows the results of a poll in which randomly selected high school students were asked if they prefer Football or Basketball. What is the marginal relative frequency of 12th graders? What is the joint relative frequency of 10th graders who like football? The table below shows the results of a poll in which randomly selected high school students were asked if they prefer virtual or traditional schools.
In this assignment you will analyze people who use the World Wide Web to collect information on travel and compare them to those who use other resources, using the techniques you learned in this module. Construct a two-way table based on a business problem statement giving observed counts. Determine the applicable degrees of freedom for the model. Compute the expected counts for the two-way table. Compute the chi-square test statistic for the two-way table.
I begin this lesson by projecting a two-way table and a multiple choice question see Launch Prompt. I want to access my students prior knowledge of frequency tables. In this exercise students need to make a judgment with respect to using the horizontal row or vertical column frequencies. The task also requires students to add two conditional frequencies, in order to determine the relative frequency needed to answer the question successfully. As my students work on the Launch Prompt I listen in on their conversations.
