Question
Chapter 7, Problem 1CS
To determine
Whether the experiments mentioned in question would be considered as ethical or unethical.
Expert Solution & Answer
Answer to Problem 1CS
Solution: The experiment would be regarded as unethical.
Explanation of Solution
In this experiment, strong alcohol is given to subjects, and strong alcohol could have harmful and damaging effects on their health. For instance, they could suffer from hallucination, addiction, or it could damage their heart or liver or any other organ. Therefore, this experiment would be regarded as unethical. In an ethical experiment, interest and welfare of subjects is given higher precedence over interest of science and society.

- 4. Dynamic regression (adapted from Q10.4 in Hyndman & Athanasopoulos) This exercise concerns aus_accommodation: the total quarterly takings from accommodation and the room occupancy level for hotels, motels, and guest houses in Australia, between January 1998 and June 2016. Total quarterly takings are in millions of Australian dollars. a. Perform inflation adjustment for Takings (using the CPI column), creating a new column in the tsibble called Adj Takings. b. For each state, fit a dynamic regression model of Adj Takings with seasonal dummy variables, a piecewise linear time trend with one knot at 2008 Q1, and ARIMA errors. c. What model was fitted for the state of Victoria? Does the time series exhibit constant seasonality? d.
