In part of your unit project, you will explain how to use Boyle's law, Charles's law, and Gay-Lussac's law, so this activity is important to prepare you for your project. Make sure you explain each step as if you were teaching it to one of your classmates. Boyle's Law: A balloon filled with helium gas has a volume of 500 mL at a pressure of 1 atm. The balloon is released and reaches an altitude of 6.5 km, where the pressure is 0.5 atm. If the temperature has remained the same, what volume does the gas occupy at this height?Charles's law: A sample of neon gas has a volume of 752 mL at 25.0°C. What will be the volume at 100.0°C if pressure is constant?Gay-Lussac's Law: At 122°C the pressure of a sample of nitrogen gas is 1.07 atm. What will the pressure be at 205°C, assuming constant volume? * YOU MUST COMPLETE THE POWERPOINT PRESENTATION OR THE ASSIGNMENT WILL BE REJECTED * "Make sure to show your work, and your answers should be provided with the correct amount of significant figures." YOU WILL RECEIVE A SCORE REDUCTION IF THE ABOVE REQUIREMENTS ARE NOT MET. 4. Gas Volumes and the Ideal Gas Law Apply In this unit, you learned about Avogadro's law and the ideal gas law. Now, you will demonstrate your understanding of these concepts by responding to the following prompts. In part of your unit project, you will explain how to use Avogadro's law and the ideal gas law, so this activity is important to prepare you for your project. Make sure you are showing each step of your work. Avogadro's Law: At STP, what is the volume of 7.08 mol of nitrogen gas?Ideal Gas Law: A gas sample occupies 8.77 L at 20°C. What is the pressure, in atmospheres, given that there are 1.45 mol of gas in the sample? "Make sure to show your work, and your answers should be provided with the correct amount of significant figures." YOU WILL RECEIVE A SCORE REDUCTION IF THE ABOVE REQUIREMENTS ARE NOT MET. 5. Diffusion and Effusion Apply In this unit, you learned about Graham's law of effusion. Now, you will demonstrate your understanding of these concepts by responding to the following prompt. In part of your unit project, you will explain how to use Graham's law of effusion, so this activity is important to prepare you for your project. Make sure you are showing each step of your work. If a molecule of neon gas travels at an average of 400 m/s at a given temperature, estimate the average speed of a molecule of butane gas, C4H10, at the same temperature. "Make sure to show your work, and your answers should be provided with the correct amount of significant figures." YOU WILL RECEIVE A SCORE REDUCTION IF THE ABOVE REQUIREMENTS ARE NOT MET.

Grossmont College Module 11 Treating Depression Lab Independent Variable Analysis
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 1980s 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 the 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 already done so, open the depression data set in the Stats at Cuyamaca College group on StatCrunch (directions - opens in a new tab).
Prompt
We will analyze the data to answer the second research question: Which of the drugs (if either) delayed the recurrence of depression longer relative to the placebo?
In the previous lab-preparation activity, we identified Treat as the explanatory variable and Time as the response variable. We also determined that we will analyze the data using side-by-side boxplots and descriptive statistics (i.e. 5-number summaries since the graphs are boxplots).
Make graphs and tables.
Use StatCrunch to produce side-by-side boxplots. (directions)
Embed your graphs into the textbox, and be sure to include the Alt Text. To recall how to embed a picture into a textbox, see the StatCrunch directions below.
Use StatCrunch to produce the descriptive statistics (a single table containing the 5-number summaries for each comparison group). (directions)
Copy and paste the StatCrunch output table into the textbox.
Analyze the data: Compare the distributions for the treatment groups as demonstrated in Unit 2. For example, compare medians and intervals of typical values. Describe the shape and any outliers. Be sure to write your comparisons so the reader can understand the context of the numbers. For example, don't just say the median is 30; instead, say something like this: on average patients taking the placebo relapsed in 30 days (Q2=30 days).
Draw a conclusion: What can we conclude from your analysis? Did one drug successfully delay a relapse of depression better than the others? What evidence supports your conclusion?
Summarize your conclusions in response to both research questions: In this lab you compared three treatments (two drugs and the placebo) using two different variables. In Part 1 you compared whether or not a relapse into depression occurred for each of the two drugs and the placebo. In Part 2 you compared the length of time until the next relapse for the two drugs and the placebo. What can you conclude in light of both analyses? Is one treatment better than the other? How does the data support your conclusion
