Use the following data set and create a mosaic plot for the relative frequencies to answer the question “Is there a difference between the number of undergraduate students who engage in research as chemistry and biology majors”.
Student Major Does Research Doesn’t Do Research
Biology Major 53 26
Chemistry Major 29 18
Homework Answers
The widths of the boxes are proportional to the percentage of Biology majors and Chemistry majors, respectively.
The heights of the boxes are proportional to the percentage of student did research or not.
This seems to show a slight difference between the number of undergraduate students who engage in research as chemistry and biology majors. It is easy to see that Biology majors in the green box on the left is slightly larger than the Chemistry majors on the right.

Read the scenario given below. With your group, examine the data set (on page 2) and decide what analysis should be done. Perform this analysis. Record your results and submit this file on Blackboard by the end of the day. Each student must submit a copy of their results. Scenario: Students are often late to class. This is distracting to both students and teachers, and is quite annoying. The school and instructors realize that some students have long commutes, but...

Read the following passage. Does the author use qualitative or quantitative data in her research project? Respondents reported a fairly low income relative to their education level. The under $20,000 response category had the highest frequency with 26% of the total responses. The $20,000-29,000 and $30,000-$39,000 categories had total respective frequencies of 14% and 18%, which puts 54% of respondents at an annual income below $40,000. This can be partially explained by the fact that the survey question asked respondents...

The SAT and the ACT are the two major standardized tests that colleges use to evaluate candidates. Most students take just one of these tests. However, some students take both. The data data42.datgives the scores of 60 students who did this. How can we relate the two tests? (a) Plot the data with SAT on the x axis and ACT on the y axis. Describe the overall pattern and any unusual observations. (b) Find the least-squares regression line and draw...

For the two variables of interest: Create a scatter plot with Percent Time Asleep as the independent variable x and Longevity as the dependent variable y. The plot must include an informative title, along with correct labels for both axes. Include a plot of the least-squares equation (see #5 below). Calculate the correlation coefficient and the coefficient of determination. Identify any data points on the scatter diagram that appear to be influential.
