Student Learning outcome: Use the Five-Number Summary to Create a Boxplot to Describe a Data Set
In this activity, you will investigate the relationship between boxplot shapes and the corresponding five-number summary.

Step 1. Review

Review the learning resources for this lesson before studying the case problem.

Step 2. Analyze

Analyze the case problem below.

The accompanying figure shows four boxplots labeled A to D. Also given are four five-number summaries, labeled I to IV. Match each five-number summary to the appropriate boxplot. Note that scales are not included on the boxplots, so you will have to consider what the five-number summary implies about the characteristics of the boxplot.

Step 3. Respond

Respond to the case problem by showing the boxplot properties, logic steps, and reasoning you used to match each figure with its corresponding five-number summary.

Student Learning Outcome (Module 4 Lesson 2): Determine Sensitivity, Specificity, False Negative, and False Positive probabilities, the Prevalence of a disease, the Predictive Value Positive, and Predictive Value Negative of a Screening Test from a contingency table.

Step 1. Review

Review the learning resources for this lesson before studying the case problem.

Step 2. Analyze

Analyze the case problem below.

The paper “Good for Men, Good for Women, bad for People: Simpson’s Paradox and the Important of Sec-Specific Analysis in Observational Studies” (Journal of Women’s Health and Gender-Based Medicine [2001]: 867-872) described a medical study in which one treatment was shown to be better for men and better for women than a competing treatment when the data for men and women were analyzed separately. However, if the data for men and women are combined, it appears as though the competing treatment is better. 

To see how this can happen, consider the accompanying data tables constructed from the information in the paper. Subjects in the study were given either Treatment A or Treatment B, and survival was noted. Let S be the event that a patient selected at random survives, A be the event that a patient selected at random received Treatment A, and B be the event that a patient selected at random received Treatment B. 

The following table summarizes data for the men who participated in the study:

Now consider the summary data for women who participated in the study:

Now consider the data summary for men and women combined:

Step 3. Respond

Respond to the case problem by writing a brief explanation of why this apparent inconsistency occurs for this data set.

Student Learning Outcome (Module 6 Lesson 2): Compute and interpret confidence intervals for proportions.

Step 1. Review

Review the learning resources for this lesson before studying the case problem.

Step 2. Analyze

Analyze the case problem below.

The article “Doctors Cite Burnout in Mistakes” (San Luis Obispo Tribune, March 5, 2002) reported that many doctors completing their residency have financial struggles that could interfere with training. In a sample of 115 residents, 38 reported working moonlighting jobs, and 22 reported high credit card debt. Suppose that it is reasonable to consider this sample of 115 a random sample of all medical residents in the United States. 

1. Construct and interpret a 95% confidence interval for the proportion of U.S. medical residents who work moonlighting jobs.

2. Construct and interpret a 90% confidence interval for the proportion of U.S. medical residents who report high credit card debt.

3. Give two reasons why the confidence interval in Part 1 is wider than in Part 2.

4. Consider the following statement: If the process of selecting a sample of size 115 and then computing the corresponding confidence interval is repeated 100 times, 95% of the resulting intervals will include the true population proportion. Is this statement correct? Why or why not?

Step 3. Respond

Respond to the case problem by writing answers to Parts 3 and 4.
