1. Here is a table that displays the population of the WHO regions in 2016. Use the information in the data to determine which region had the highest proportion of HIV among its residents in that year.
2. Create a graph that shows the percentage of those receiving ARTs globally and time.
3. You want to compare different regions and their performance with providing ARTs to their people living with HIV. Which measure is better to use to make these comparisons, "Reported the number of people receiving antiretroviral therapy" or Estimated percent of antiretroviral therapy coverage among people living with HIV." Why?
4. Create a side-by-side boxplot of the WHO regions' estimated percent of antiretroviral therapy coverage among people living with HIV. Be sure to write several sentences describing the similarities and differences of the regions.
5. Is the mean estimated percent of ART therapy coverage in South-East Asia significantly different than the mean estimated percent of ART coverage in the Eastern Mediterranean region? Use a 0.10 significance level to test this. Be sure to complete all five steps of the hypothesis testing process.
