1.    A researcher would like to know whether there is a consistent, predictable relationship between verbal skills and math skills for high school students. A sample of 200 students is obtained, and each student is given a standardized verbal test and a standardized math test. Based on the test results, students are classified as high or low for verbal skills and for math skills. The results are summarized in the following frequency distribution:  

                                                          Verbal Skills

                                   High                        Low

Test at the .05 level of significance whether there is a significant relationship between verbal skills and math skills.

df = __________

Χ² = ________

CV = _________

Is there a significant relationship between verbal skills and math skills? a. YES b. NO

Choose the best report:

a. There is a consistent predictable relationship between verbal skills and math skills for high school students, n = 200, df 1 X² = 15.84.

b. There is a significant difference between verbal skills and math skills; X² (2, n=200) = 15.84, p < .05.

c. There is a significant relationship between verbal and math skills X² (1, n=200) = 15.84, p < .05.

d. We retain the null, that there is no relationship between verbal skill and math skills for high school students. The X²= 0.5 with a CV (1) = 3.841. There is no effect because we retained the null. But if you were to calculate it, it would be = 0.05.

e. While running a basic analysis test, it was found that there is significant relationship skills between verbal skills and math skills. With a X² = 17.68 and utilizing 1 df, the cv = 3.841.

CASE 4 Meron is a Health Extension Practitioner, who frequently goes to the local school to conduct health education sessions. Whenever she goes to the school she carries her posters, leaflets, charts and other educational materials with her. After class she asks her students in a feedback session about how the session has gone. She is always happy with the feedback she is given.

.

Question 1: One day Meron went to school to create awareness on sanitation, but on that day she did not carry her educational aids with her. At the end of the class the feedback from the students is not as good as previously.

.

Question2: Assume that in one of the villages you are working in you observed more malaria cases than previously had occurred. You had gone to the area and observed that there is one place favourable for mosquitoes to breed. You now want to use health education to enable the community to destroy the mosquito breeding site. Who do you think you should talk to first about this problem?

.

Question3: Why do you think that it is a good idea to include representatives of your target audience when you are planning your health education activities?

.

Question4: Fatuma is a Health Extension Practitioner. While conducting a health education session on breastfeeding she said to her audience ‘I think HIV/AIDS might be transmitted from mother to child through breastfeeding’. What did you observe from the above scenario? How would you expect Fatuma to respond?

.

Question5: Imagine that you are conducting a health education session in your local community. During your teaching you say ‘I think female genital mutilation (FGM) is harmful’ or ‘I think tobacco causes cancer’. What would be a better way of putting this?

Consider a small economy composed of six people: Nick, Rosa, Tim, Alyssa, Crystal, and Brian. Each person's employment status is described in the following table.

Based on the criteria used by the Bureau of Labor Statistics (BLS), identify each person’s status as employed, unemployed, “not in the labor force” (if not in the civilian labor force but still part of the adult population), or “not in the adult population” if not in the civilian adult population.

Problem 9-20 (Algo) Critique a Report; Prepare a Performance Report [LO9-1, LO9-2, LO9-3, LO9-4]

TipTop Flight School offers flying lessons at a small municipal airport. The school’s owner and manager has been attempting to evaluate performance and control costs using a variance report that compares the planning budget to actual results. A recent variance report appears below:

After several months of using these reports, the owner has become frustrated. For example, she is quite confident that instructor wages were very tightly controlled in July, but the report shows an unfavorable variance.

The planning budget was developed using the following formulas, where q is the number of lessons sold:

  
Required:

2. Complete the flexible budget performance report for the school for July. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)

Assignment #3: Independent Samples T test Conduct an Independent Samples T test to answer the questions based on the following scenario. (Assume a non-directional research hypothesis (two-tailed test) and a level of significance of .05) The superintendent who collected data for Assignments 1 and 2, continued to examine the district’s data. One question that concerned the superintendent’s constituencies was the difference between the school performance scores of the superintendent’s district and a neighboring district that had similar demographic and socio-economic characteristics.

The superintendent collected the following information:

School performance scores for superintendent’s district: 72 70 70 71 68 74 66 80 71 74 68 74 74 70 76 67 65 59 72 81 82 83 68 78 80 69 75

School performance scores for comparison district: 71 62 62 71 65 74 61 60 67 63 62 71 66 62 61 71 66 68 72 65 71 86 71 89 67 73

1. What are the mean and standard deviation for the superintendent’s district? 2. What are the mean and standard deviation for the comparison district? 3. State an appropriate null hypothesis for this analysis. 4. What is the observed or computed value of t? 5. What is the value of the degrees of freedom that are reported in the output (equal variances assumed)? 6. What is the reported level of significance? 7. Based on the reported level of significance, would you reject the null hypothesis?

Calculate the predicted self-control score for a person living in a good neighborhood who is 18 years old, male, who scores a 12 on parental supervision, a 15 on parental responsiveness, a 10 on school socialization, and whose mother smoked during pregnancy.  Then, calculate the self-control score for a person living in a good neighborhood who is 21 years old, female, who scores an 8 on parental supervision, a 10 on parental responsiveness, a 6 on school socialization, and whose mother smoked during pregnancy.  If having low self-control is a significant predictor of delinquency, which individual (#1 or #2) would be more at risk of engaging in delinquency?

Table 1 below provides slopes, standard errors, and betas for several variables used to predict levels of self-control (higher scores = lower self-control) for respondents living in “good” and “bad” neighborhoods.
