Social Psychology, Psy 318 Generate an example of a time when you would draw a dispositional inference from someone’s behavior (do not use the example of lateness I used in class). Use either (Kelley’s) Covariation Theory or (Jones and Davis’s) Correspondent Inference Theory (not both) to explain why you would draw a dispositional inference about another person’s behavior. Make sure to describe the behavior /situation with sufficient detail, say which theory you are using, and apply all 3 aspects of the relevant theory to this behavior / situation. Additional tips: -Do not use ‘being late / lateness’ as an example.

A nonscientist friend of yours asks how findings in a wormorfly can be relevant to human biology. Explain to your friend the importance of model organisms in molecular biology research.

1. Compare and contast one-dimensional SDS-PAGE and two-dimensional gel electrophoresis of proteins.

2. You have purified a protein. When you subject it to SDS-PAGE, two bands are seen. Provide a possible explanation and describe how you could test your hypothesis.

3. Compare and contrast the steps in production of polyclonal and monoclonal antibodies.

4. A chromatographic column in which oligo-dT is linked to an inert substance is useful in separating eukaryotic mRNA from other RNA molecules. On what principle does this column operate?

5. You plan to use the polymerase chain reaction to amplify part of the DNA sequence shown below, using oligonucleotide primers that are hexamers matching the regions shown in red. (In practice, hexamers are too short for most purposes). State the sequence of the primer oligonucleotides that should be used, including their polarity (5?3?), and give the sequence of the DNA molecule that results from amplification.

6. Complete the incomplete diagrams below to show the key structural difference between an NTP, dNTP, and ddNTP (e.g., CTP, dCTP, ddCTP).

What do “d” and “dd” stand for?

Explain why ddNTPs are called "chain terminators" in DNA sequencing reactions.

As part of a rapidly growing firm located in the US, your CEO has asked you to find out more about US requirements for exporting. Using the following link, Export.Gov, describe what you find about common export documentation. Select at least one of the documents and describe its purpose in greater detail.

Suppose that you have an unknown culture that is growing within your culture dish. You wish to stain it in order to identify it. Describe, in full detail, the process you would go through to make a slide for that culture, and which staining technique you would use. (Hint: which stain would give you the most information about morphology and specific properties)

Genetic theory predicts that, in the second generation of a cross of sweet pea plants, flowers will be either red or white, with each plant having a 25% chance of producing red flowers. Flower colours of separate plants are independent. Let X be the number of plants with red flowers out of 20 plants selected at random from the second generation of this cross. (a) What is the probability distribution of X? [3] (b) Calculate: (i) the mean and standard deviation of X. [3] (ii) P( X > 8) [2] (iii) P( 4 ≤ X ≤ 10) [2] (c) If only 3 of the 20 plants had red flowers, would this be an unusual sample? Calculate a probability and use it to justify your answer

Read the following scenario and complete each of the problems below:

A flashlight company claims that the new bulb in its heavy duty flashlight will average 246 hours of light. A statistics student decides that he/she wants to test this claim at a 5% level of significance to determine if there is evidence to support the claim. The student randomly selects and test 15 flashlight bulbs and records how long the bulb last until it burns out. Assume the life of the bulb is normally distributed. The data is in the table below:

Trial:   1      2             3             4            5     6              7              8             9            10            11           12   13            14           15

A. Based on a histogram or box-plot of the data, what is the shape of the distribution (normal, skewed left, skewed right, uniform, etc.)? Explain why you can conduct a hypothesis test on the given data. (Compose your answer)

B. Evaluate the claim based on the following assumption: The standard deviation of the population is 7.4 hours. 1. Identify the type of test you will use to test the claim that the flashlight will average 246 hours of light. Explain your answer 2. State the null and alternate hypotheses. 3. Conduct the hypothesis test and determine the p-value. 4. State your conclusion about the claim that the flashlight will average 246 hours of light. 5. Construct a 95% confidence interval for this study.

Context/Situation:

A manufacturer and distributor of home appliances, ABC, Inc. in Tulsa Oklahoma owns the name brand “Hercules” and wishes to manufacture or source, and market washing machines. John Smith the President is tasked with “Developing and Managing the Supply Chain for Washing Machines”. The Marketing Manager, Harold Casey is given the task of reporting to John Smith and “Managing the Channels of Distribution” for the washing machines division.


Assignment:

Please evaluate the context/situation and then explain in detail what would be the DIFFERENCES in the assignments of John Smith and Harold Casey. Use your response to also detail how channel management in this case would differ from supply chain management. Please use the chapter in the textbook as well as any internet based research you can do on the subject. Expected length of answer: One page, single space, Times New Roman, Font Size 12

13. In your opinion, what are the three more important resources to manage in an organization? Explain in detail the logic of your answer.

14. Concepts such as ‘socio-technology,’ ‘technology-structure,’ ‘technology-system;’ what do they have in common? Provide examples

15. Provide an example of Competitive Advantage and of Comparative Advantage. Explain the difference between them.

(1 point) In a study of red/green color blindness, 550 men and 2300 women are randomly selected and tested. Among the men, 47 have red/green color blindness. Among the women, 7 have red/green color blindness. Test the claim that men have a higher rate of red/green color blindness.
(Note: Type ‘‘p_m′′‘‘p_m″ for the symbol pmpm , for example p_mnot=p_wp_mnot=p_w for the proportions are not equal, p_m>p_wp_m>p_w for the proportion of men with color blindness is larger, p_m<p_wp_m<p_w , for the proportion of men is smaller. )

(a) State the null hypothesis:

(b) State the alternative hypothesis:

(c) The test statistic is

(e) Construct the 9595% confidence interval for the difference between the color blindness rates of men and women.
