Does the location such as States or Zip codes as well as weather conditions have any influence on the sales?" Please AdviseThe number of hospitals in the United States has been declining for many years. In 1990, there were 6155 hospitals; but in 2010, there were only 4985. Assuming that this trend is linear, use t (years since 2000) and N (number of hospitals in the United States). According to your model, what is the number of hospitals in the United States in 2016? {Your final answer will be number only}
