Exercise 12 For this exercise, different studies/datasets will be introduced. Use the three codes above to solve questions about these datasets. Dataset 1) "In this world, nothing can be said to be certain, except death and taxes" Benjamin Franklin, 1789. Researchers were interested in testing if taxes had an influence on death rates in the United States. In particular, they were interested in seeing if there was an effect of raising the estate (inheritance) tax on 3) Based on your answer to #2, was raising the estate tax associated with a change in the mean death rate in the United States Population from 1917-1942? Dataset2) Weddell seals live in the Antarctic and conduct long dives in cold ocean water to forage for fish. The dives can be physiologically strenuous for the seals. Feeding dives may be more costly than nonfeeding dives because the seals will need to maneuver quickly and accelerate to hunt fish. Researchers were interested in comparing the metabolic cost of a feeding dive and a nonfeeding dive of the same duration. They measured oxygen concentrations before and after dives and calculated the oxygen used by the seals as an indication of metabolic cost. They then examined ten seals and measured oxygen used during a nonfeeding dive with oxygen used during a feeding dive of the same time duration. Because each seal was measured for both types of dives, this is a paired dataset. dataset: weddelt variable1: weddellsoxygenUseFeeding variable2: weddellsoxygenUseNonfeeding 3) Based on your answer to #2, was raising the estate tax associated with a change in the mean death rate in the United States Population from 1917-1942?
