SCENARIO 4

You are interested to find the learners’ perspective “whether online learning is better than contact learning”. You decide to undertake a qualitative research to find an answer.

QUESTION 4                                                                                                                                                                                       [25 marks]

Develop 10 structured interview questions to collect the learners’ perspective. Conduct at least 5 interviews( you may do to telephonic interviews). Transcript of the interview conducted should be included as part of the answer. Analyse the data collected using content analysis. You are expected to include all the steps in the analysis process. Conclude the research with a statement based on analysis of the data.   

Which probability rule would be used to determine the probability of getting into both your first choice graduate program AND getting an interview at your first choice post-graduation?

Solve for the probability of BOTH events occuring if the probability of getting into your first choice graduate program is estimated to be 25% and getting an interview at your first choice job post-graduation is estimated to be 50%.

If the robt = 0.20 and the df = 70 and the test was two-tailed, what is the rcv ?

Given the values provided in #17, should you reject or fail to reject the null hypothesis?

Significance level is 0.05

As a sociologist, you are interested in investigating the stress levels of people who live in urban versus rural areas. You randomly select 80 urban residents and 70 rural residents to interview. Respondents from urban areas experience an average of 13.2 stressful experiences per week with a standard deviation of 3.2 times. Respondents from rural areas experience an average of 11.5 stressful experiences per week with a standard deviation of 2.1 times. We set the alpha level at 0.01. Please perform the appropriate hypothesis test using five steps.

A 500 word essay on McLuhan

-Determine if McLuhan used the critical perspective in his thinking in the medium is the message.

Specifically, does McLuhan:

1. Question commonly held assumptions?

2. Expand the bounds of debate?

3. Aim for the betterment of society?

Is McLuhan using the critical perspective? If so, explain how his thinking utilizes the above characteristics. If not, explain how his approach differs from the above.

To successfully complete this assignment, carefully re-read the McLuhan Playboy interview, the chapter from Understanding Media, and review the lectures on McLuhan and the critical perspective.

In 2015, a delivery company purchased a fleet of local delivery trucks for $175,000. These are 5 year assets. This company pays federal tax at a rate of 23% per year. (a) Develop a MACRS depreciation table for this asset, and compute the post-tax income of this company using their gross sales income given below. (b) Is this a good investment if MARR = 25% per year? (c) The company sold the trucks in September 2020 for $18,000. What are the tax implications? Year Gross Annual Income di Di Taxable Income Tax paid Post-Tax income 2015 $250,000 2016 $350,000 2017 $30,000 2018 $150,000 2019 $165,000 2020 $65,000

A university wants to determine if students from different majors are equally likely to be cited for academic dishonesty. They average instances of documented cheating across 10 years for three different academic majors and find the following results: Business Administration (M = 5.1; N = 10), Fine Art (M = 1.9; N = 10), and Nursing (M = 3.2; N = 10). They also calculated the between-group and within-group sum of squares (SS_B = 301.6; SS_W =1343.8). Use a one-way ANOVA (where α = .01) to determine if there are significant differences in cheating rates by major.

1. Identify the alternative hypothesis (F tests are always nondirectional)
2. List your degrees of freedom (within)
3. List your degrees of freedom (between)
4. List your mean squares between groups
5. List your mean squares within groups
6. List your F test statistic
7. List your critical F value(s)
8. Are there statistically significant differences in cheating between majors? (Yes/No)
9. Calculate partial eta-squared (η²) for the effect of major on cheating rates (list as decimal, 0.xx)
10. Calculate Tukey’s HSD
11. Use Tukey’s HSD to determine if the difference in cheating rates between Business Administration majors and Fine Art    majors is statistically significant (Yes/No)

A random sample of 20 college professors is selected from all professors at a university. The following list gives their ages: 27, 52, 49, 63, 60, 57, 48, 53, 47, 42, 51, 54, 62, 60, 49, 58, 56, 47, 44, 49 [a] (1 point) What is the POPULATION in this problem? [b] (1 point) What is the SAMPLE? [c] (1 point) State whether the ages of professors are QUANTITATIVE or QUALITATIVE? [d] (1 point) If quantitative, is it DISCRETE or CONTINUOUS? [e] (6 points) Using the age sample data above, find the mean. median, mode, range. standard deviation and variance. Be sure to include the units in your answers. You do not need to show work. Round to 1 decimal place. [f] (2 points) Find the inter-quartile range of the age sample data. Show work. [g] (4 points) Find the "fences". Then use the fences to determine whether there are any outliers. Show all work. [h] (4 points) Draw a boxplot. Draw a boxplot. (Label the 5 number summary. Be sure to include outlier(s) if any.)

A random sample of 4 college students was drawn from a large university. Their ages are 22, 17, 23, and 20 years.

a) Test to determine if we can infer at the 5% significance level that the population mean is not equal to 20.

b) Interpret your conclusion.
