Your college has also been working on this data set, and found that the number of casual sexual partners is significantly different between those who reported having known someone ill with AIDS and those who did not (p=0.04). The average age of first sexual intercourse for those who reported having known someone who was ill was 16.37 years compared to 16.16 years for those who did not (Table 1). The difference in the average age of first sexual intercourse between those reporting knowing someone ill and those who do not is relatively low (<3 months). Why might such a small change be statistically significant? Use your understanding of the t-test equation and mathematical basis to justify your answer.
2. For the following question, can you just tell me the appropriate test to choose and justify?
a) Does age of first sexual intercourse differ significantly between religious groups?
b) Was there a statistically significant change in condom use between 1991 and 1996?
c) Does the number of casual sexual partners in the past 12 months differ significantly by education level?
d) If you were asked to determine whether there was a statistically significant decrease in the average number of casual sexual partners (over the past 12 months) for Ugandans between 1991 and 1996, what test(s) could you use and why?
Here is the description of my data:
