PSYC 8754 Walden University Generalized Work Activities Scales Discussion
The Occupational Information Network (O*NET) is a source of occupational information maintained by the United States Department of Labor. The database contains standardized descriptions of various occupations. Each year, the database is updated after O*NET personnel survey a random sample of incumbent workers in a broad range of occupations. The O*NET Data Collection Program provides several hundred rating scales that are based on the responses of the sampled workers. There are four different questionnaires for the incumbent workers to complete related to occupation and employee characteristics. Personnel consultants complete a questionnaire that focuses on the sample workers’ abilities (O*NET, n.d.).
As a potential personnel consultant, you might collect this data and incorporate it into the next version of the O*NET database. You need to ensure that your rating is reliable by checking that your measure is consistent and the measurement error is reported. You can test reliability using various models. For example, you can test the consistency of your measure through interrater reliability by examining the percentage of agreement between raters.
For this Application Assignment, review the media, “Employee Observation” and “Employee Interview,” for the job analysis. Presume the purpose of the job analysis will be to construct a selection instrument for the job displayed in the media.

The Assignment (3–5 pages)
Complete the abilities scales from the O*NET using the media, “Employee Observation” and “Employee Interview,” to provide the ratings of the abilities of the incumbent worker. Your ratings are only for your analysis and not for submission.
Analyze the results from the O*NET generalized work activities (dataset provided in this week’s Learning Resources). For your analysis:
Calculate a mean rating for each question on the survey.
Use SPSS to calculate interrater reliability and agreement statistics (see the “SPSS Supplementary Document” for instructions).
Explain the generalized work activities scales and your ratings of the abilities scales on the O*NET.
Explain the statistical findings and the interrater analysis for the generalized work activities scales.
Summarize both the abilities and work activity analyses you have conducted on the employee in the media.

I need solutions to the problems below
1.The world’s smallest mammal is the bumblebee bat, also known as the Kitti’s hog nosed bat. Such bats are roughly the size of a large bumblebee! Listed below are weights (in grams) from a sample of these bats. Test the claim that these bats come from the same population having a mean weight equal to 1.8 g. Perform a complete analysis: The six step hypothesis test with a conclusion that includes a statistical conclusion, a confidence interval and a scope of inference (as best as can be done with the information above … I could see many correct answers with the vagueness of the description of the sampling mechanism.)Sample: 1.7 1.6 1.5 2.0 2.3 1.6 1.6 1.8 1.5 1.7 2.2 1.4 1.6 1.6 1.6 2.In the United States, it is illegal to discriminate against people based on various attributes. One example is age. An active lawsuit, filed August 30, 2011, in the Las Angeles District Office is a case against the American Samoa Government for systematic age discrimination by preferentially firing older workers. Though the data and details are currently sealed, let’s suppose that a random sample of the ages of fired and not fired people in the American Samoa Government are listed below:Fired34 37 37 38 41 42 43 44 44 45 45 45 46 48 49 53 53 54 54 55 56Not fired27 33 36 37 38 38 39 42 42 43 43 44 44 44 45 45 45 45 46 46 47 47 48 48 49 49 51 51 52 54a.Perform a permutation test to test the claim that there is age discrimination. Provide the Ho and Ha, the pvalue, and full statistical conclusion including the scope. Note: this was an example in Live Session 1. You may start from scratch or use the sample code and powerpoints from Live Session 1. b.Now run a two sample t-test appropriate for this scientific problem (Note: we may not have talked much about a two-sided versus a one-sided test. If you would like to read the discussion on pg 44 (Statistical Sleuth), you can run a one-sided test if it seems appropriate. Otherwise, just run a two-sided test as in class. There are also example in the Statistics Bridge Course). Be sure to include all six steps, a statistical conclusion and scope of inference.c.Compare this p-value to the randomized p-value found in the previous homework.d.The jury wants to see a range of plausible values for the difference in means between the fired and not fired groups. Provide them with a confidence interval for the difference of means and an interpretation.e.Given the sample standard deviations from SAS, calculate by handi.Pooled standard deviation (sp)ii.The standard error of () 3.In the last homework I mentioned I polled my Business Stats class here at SMU and asked them how much money (cash) they had in their pocket at that very moment. The idea was that we wanted to see if there was evidence that those in charge of the vending machines should include the expensive bill / coin acceptor or if it should just have the credit card reader. However, I met a professor from Seattle University last year and asked her to poll her class with the same question. Below are the results of our polls. SMU34, 1200, 23, 50, 60, 50, 0, 0, 30, 89, 0, 300, 400, 20, 10, 0Seattle U20, 10, 5, 0, 30, 50, 0, 100, 110, 0, 40, 10, 3, 0a.Run a two sample t-test to test if the mean amount of pocket cash from students at SMU is different than that of students from Seattle University. Write up a complete analysis: All 6 steps including a statistical conclusion and scope of inference (similar to the one from the powerpoint.) (This should include identifying the Ho and Ha as well as the pvalue.) Also include the appropriate confidence interval.b.Compare the pvalue from this test with the one you found from the permutation test from last week. Provide a short 2 to 3 sentence discussion on your thoughts as to why they are the same or different. 4. a.Calculate the estimate of the pooled standard deviation from the Samoan discrimination problem in question 2 above. Use this estimates to build a power curve. Assume we would like to be able to detect effect sizes between 0.5 and 2 and we would like to calculate the sample size required to have a test that has a power of .8. Simply cut and paste your power curve and SAS code. HINT: Instead of using groupstddevs, use stddev since we are using the pooled estimate. b.Now let’s say that we decided that we may be able to live with slightly less power if it means savings in sample size. Provide the same plot as above but this time calculate curves of sample size (yaxis) vs effect size (.5 to 2) (x axis) for power = 0.8, 0.7 and 0.6. There should be three plots on your final plot. Simply cut and paste your power curve and SAS code. HINT: , use stddev since we are using the pooled estimate. c.Using your last plot, estimate the savings in sample size from a test aimed at detecting an effect size of 0.8 with a power of 80% versus a power of 60%.
