Use hand drawn pictures to describe your understanding of colligative properties of solutions at the particulate level. You should use each molecule drawn to represent 0.01 mol of that substance. You should be sure to include all components of your understanding in the representation. The molecules you are required to include in your explanation are glucose, magnesium chloride, aluminum sulfate. Make sure you have appropriate atom/molecule size. Note: You should be sure to include those components like concentration, effects on vapor pressure, effects on the algorithmic (mathematical process) problem solving solution, and what do the algorithmic solutions indicate. Each picture should have an explanation of every detail you felt was important.

Two types of medication for hives are being tested. The manufacturer claims that the new medication B is more effective than the standard medication A and undertakes a comparison to determine if medication B produces relief for a higher proportion of adult patients within a 30-minute time window. 20 out of a random sample of 200 adults given medication A still had hives 30 minutes after taking the medication. 12 out of another random sample of 200 adults given medication B still had hives 30 minutes after taking the medication. The hypothesis test is to be carried out at a 1% level of significance.
State the null and alternative hypotheses in words and in
statistical symbols. (3 points)
What statistical test is appropriate to use? Explain the rationale
for your answer. (3 points)
Would the test be right-tailed, left-tailed or two-tailed? Explain
the rationale for your answer. (3 points)

Having trouble with this question. Do I make a graph from 0 to 1 with ten minute intervals so that I would have 6 rectangles? I think this is right.
A bug is crawling at a velocity of f(t)= 1/2-t meters per hour,
where 0 ≤ t ≤ 1 and t is in hours.
a) Find both the left-endpoint and right-endpoint approximations
for the area under the graph f(t) during this hour. Use 10-minute
increments (be careful about units).
b) Explain what your results to Part a) mean about this bug.

Discuss the requirements for each of the following components and discuss which of the processes you would choose to make the product. Please provide references where possible.
1. Bicycle Gears.
An example is shown below:
Example: An ashtray
Select all materials possible in making ashtray e.g. stainless steel and explain the properties of stainless steel. Hence choose the best material based on production purposes.
Explain briefly all the process involved (e.g. casting, forging, etc) in making the product for the selected materials. Explain in detail the best process that your group had chosen for making of the product. (Eg: Molding, include diagram.)
Conclusion to why your group had chosen the materials and process for every item above.
Overall conclusion to the above case study e.g teamwork, what you had gained from the case study, etc.

Use the counting techniques from the last chapter. A bag contains two red marbles, three green ones, one fluorescent pink one, two yellow ones, and three orange ones. Suzan grabs three at random. Find the probability of the indicated event.
She gets all the red ones, given that she gets the fluorescent pink one.

People generally tend to have strong feelings about the existential, humanistic and positive psychology approaches. Some consider them more holistic because they can embrace the more spiritual and esoteric aspects of the human condition. Others consider them unstructured and unscientific.
What do you think?
Discuss
Post a thoughtful and reflective argument explaining the advantages and the disadvantages of the existential, humanistic and positive approaches to studying personality. Be thorough and give specific detail.
You may draw on the material in the text, but make sure to add your own thoughts and ideas about the perspectives in this module. How do they contribute to a better understanding of human personality and behavior? How do they fall short in doing so? How are they useful? Are they potentially damaging in any circumstances?
