## Problem set 2: parasites and traffic accidents The parasite * oxoglasna goad:i* infects warmblooded vertebrates, including 3653% of humans, in most countries. A short phase of acute infection is followed by a latent phase [lifelong presence of * axoglasma* cysts in nerve and muscle tissues), in which infected subjects are considered to be asymptomatic. Researchers noticed, however, that some subjects with latent infections had longer reaction times in laboratory tests, and speculated that latent infection might influence the performance of subjects in reallife situations. To find out, the researchers surveyed a sample of 15 to 29yearold drivers from Prague who had been involved in traffic accidents. Each driver was given a blood test at the time of the accident {to rule out intoxication), which revealed any latent infection by *ngoglasha*. The researchers also surveyed a control sample of drivers of the same age living in the same area who had not been in any accidents. The data are contained in the file 'drivers.csv', which you can load by running the chunk below. '{r} =' ' a sun tais caunk to load tre data for Problen set 2 drivers
