Describe the three major categories of data (time-series, cross-sectional, and panel).
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.
Using satellite imagery to aid agriculture grain production has been done on a limited scale as far
back as the 1970's when NASA first launched the Landsat satellite. But it has only been recently that
the satellite images, including GPS satellites, and data from typical farm operations have been
integrated together to provide a data driven innovative technology that improves the efficiency and
productivity on farms. In one study samples were taken on wheat yields in the State of Washington
which historically had average yields of 35.6 bushels per acre with a standard deviation of 3.7
bushels per acre. Suppose that a random sample of the wheat yields on 40 different farms was taken
and the sample mean for the wheat yields was computed, and you are interested in a probability
about the sample mean.
