Strands of human hair absorb elements from the bloodstream and provide a historical record of both health and the use or nonuse of chemical substances. Hair grows at the rate of about one – half inch per month, and a person with long hair might be accused or absolved on the basis of a segment of hair that sprouted many months or years ago. By separately analyzing sections of the hair strand, scientists can even approximate the periods of time during which drug use was heavy, moderate, light or altogether absent. If a transit employee provides a strand of hair for drug testing, state the null and alternative hypothesis in verbal terms, then identify what would constitute a Type I error and Type II error in this situation.
