The NutritionStudy dataset contains data collected from a cross-sectional study that aimed to investigate the relationship between personal characteristics and dietary factors, and plasma concentrations of retinol, beta-carotene, and other carotenoids. Study subjects were patients who had an elective surgical procedure during a three-year period to biopsy or remove a lesion of the lung, colon, breast, skin, ovary, or uterus that was found to be non-cancerous. Which set of hypotheses should be used for testing this claim? Is there evidence that all patients who have this elective surgical procedure, as represented by the sample in this study, have a mean cholesterol intake of less than 250 mg per day? Since we are interested in looking at a hypothesis test for a single mean, we would like to use a t-distribution. How many degrees of freedom would the null distribution have?

4. In the class, we discussed the neutrality of monetary policy in the long run. The theory originates from the quantity theory of money (QTM), which states that an exogenous change in the money volume by money authorities can affect nominal variables like prices and wages in the long run but have no impact on real variables like output, employment, and interest rates. In its simplest form, the QTM looks like the following: In the long run, V and T are considered constant. While learning the AS-AD model, we discussed the self-correction mechanism of an economy in the long run. If fiscal policies influence the aggregate demand, employment, and output in the short run (like monetary policy) but not necessarily can affect the potential output in the long run, then why is it not considered neutral like monetary policy? What do you think are different in the mechanisms and effects of these two policies that might lead to the distinction? Explain carefully using either expansionary or contractionary policy example (if you discuss using an expansionary fiscal policy situation, then do the same for monetary policy).
