3. This is observation from previous years about the impact of students working while they are enrolled in classes, due to students too much work, they are spending less time on their classes. First, the observer need to find out, on average, how many hours a week students are working. They know from previous studies that the standard deviation of this variable is about 5 hours. A survey of 200 students provides a sample mean of 7.10 hours worked. What is a 95% confidence interval based on this sample?

In this activity, you will investigate the first question
related to the study described below.
Some features of this activity may not work well on a cell phone
or tablet. We highly recommend that you complete this activity on a computer.
Here are the directions and grading rubric for
the Learn by Doing discussion board exercises.
A list of StatCrunch directions is
provided at the bottom of this page.
Context
Clinical depression is a recurrent illness
requiring treatment and often hospitalization. Nearly 50% of people who have an
episode of major depression will have a recurrence within 2-3 years. Being able
to prevent the recurrence of depression in people who are at risk for the
disease would go a long way to alleviate the pain and suffering of patients.
During the 1980's the federal government, through the National Institutes of
Health (NIH), sponsored a large clinical trial to evaluate two drugs for
depression. There were 3 treatment groups. Patients received either Imipramine
(Imip), Lithium (Li), or a Placebo (Pl). Researchers randomly assigned patients
to one of the 3 treatment groups and followed them for 2-4 years to track any
recurrences of depression.
(Prien et al., Archives of General Psychiatry, 1984).
Variables
·
Hospt: Which hospital the patient was from: Labeled
1, 2, 3, 5 or 6
·
Treat: 0=Lithium; 1=Imipramine; 2=Placebo
·
Outcome: 0=Success 1=Failure (recurrence of
depression)
·
Time: Number of weeks until a recurrence (if
outcome=1) or until study ended (if outcome=0)
·
AcuteT: How long the patient was depressed before
the start of the current study, measured in days
·
Age: Age in years
·
Gender: 1=Female 2=Male
Data
If you have not done so already, download
the depression datafile (as always, if a login box
opens, just close it and then download the file). Then upload the file in
StatCrunch.
Prompt
We will analyze the data to answer the 1st
research question: Which of the drugs (if either) was more successful
in preventing the recurrence of depression relative to the placebo?
In the previous lab-preparation activity, we determined that we
will analyze the data using a two-way table and conditional percentages.
1. Use StatCrunch to produce a two-way
contingency table. (directions)
Copy the table in your StatCrunch output window and paste it in your initial
discussion post. (directions)
After you paste the content of the your StatCrunch output window into your
discussion post, keep the table titled Contingency table results: and
delete the Chi-Square results: table.
2. Analyze the data in your two-way table by
finding appropriate conditional percentages. Write each
conditional percentage as a ratio (e.g. 25 out of 40) and as a percentage (e.g.
25/40 = 62.5%). Then write a sentence that explains the meaning of the
percentage in the context of the research question.
3. Draw a conclusion. Based on this study, which
drug was the most effective in preventing the recurrence of depression? Support
your conclusion using conditional percentages.
