Extracted text: Using the following data from 5 states, we are asked to investigate the hypothesis that the number of doctors per capita in a state influences life expectancy (note this is not formal hypothesis testing, as we're not doing a test of statistical significance, but we can still interpret results as being consistent with a hypothesis, or not). Specifically, we're interested in whether the number of medical doctors per 1000 state residents impacts the average lifespan for these states. Medical Doctors Average State per thousand lifespan in years residents Massachusetts 4.53 80.5 Pennsylvania 3.32 79.7 Michigan 2.88 79.2 Indiana 2.20 76.6 Wisconsin 2.60 80.3
