Final answer:
To find the percent of individuals who did not have Zika, given that they tested positive for the virus, subtract the percent of individuals who had Zika from 100%. In this case, the percent of individuals who did not have Zika is 91.8%.
Step-by-step explanation:
To find the percent of individuals who did not have Zika, given that they tested positive for the virus, we need to look at the relative frequency table. The table shows that 8.2% of individuals who tested positive for Zika actually had the virus, while 2.3% of individuals who tested positive did not have Zika. Since the table provides information in terms of percentages out of 100, we can subtract the percent of individuals who had Zika from 100% to find the percent of individuals who did not have Zika.
Therefore, the percent of individuals who did not have Zika, given that they tested positive for the virus, can be calculated as:
100% - 8.2% = 91.8%
