Question

1. HIV knowledge in the city of Chicago. In the city of Chicago, for the year 2016, the highest percentages of persons living with HIV/AIDS (PWHA) were found in neighborhoods of “X” (2.2%) and “Y” (1.8%). That same year, the neighborhoods of “A” (0.3%) and “B” (0.3%) were found to have the lowest percentages of PWHA. Suppose a DNP student conducting her capstone project selects a random sample of 10 males (age 21-45 years) each from the four neighborhoods of Chicago and obtains their responses to the HIV-KQ-18 scale (an 18-item questionnaire that assesses HIV transmission knowledge). Data are presented in Table below. The DNP student is interested in determining whether there is any evidence of a difference in knowledge of HIV transmission across the groups of men representing each of the four Chicago neighborhoods. Table 1: HIV Knowledge Scores Neighborhood X Neighborhood Y Neighborhood A Neighborhood B 13 12 14 11 7 14 18 10 17 14 10 9 12 11 3 4 13 5 6 4 10 12 4 9 18 8 7 13 9 6 9 17 6 12 9 9 10 12 8 9 a. What type of analysis should be used to answer this question? Why did you choose that type of analysis? Your options are: one sample t-test, one sample z-test, Two sample t-test, chi-square, ANOVA, and paired t-test. Check if the conditions for reliable use of the test are met. [2 points] b. Does the data support the hypothesis that neighborhood is related to HIV knowledge score? Show any Statcrunch output used to answer the question. [2 points] c. Interpret your finding in context. Describe your findings as if you are interpreting it to a lay person (a person not familiar to hypothesis testing). [2 points]

Explanation / Answer

PART A.

One factor ANOVA

PART B.

given data

Null Hypothesis Ho : µ1 =µ2 =µ3 =µ4

Alternative Hypothesis : µ1 µ2 µ3 µ4

Hence Value of |F cal| < |F Crit|and Here We Accept Ho

no evidence of a difference in knowledge of HIV transmission across the groups of men
