Please clearly state which part the answer is for.

As of January 31, 2021, there are 48 different models of Electric Vehicles (EV) available for sale in British Columbia (BC). Among them, 20 of them would qualify for incentives provided by the Canada federal and BC governments and the amount ranges from $3,000 to $8,000. A random sample of 100 EV owners/drivers was drawn, and they were asked what is their view about environment issues like Global Warming.

a) About 42% (20 out of 48) of the EV that are qualified for the incentives provided by the two governments. Is the value (42%) a parameter or statistic? Briefly justify your answer.

b) Suppose the objective of the study is to estimate how general drivers (owners of electric vehicles and gasoline-driven vehicles) view environment issues like Global Warming. Does the situation involve any selection bias? Please provide a detailed and logical justification.

c) Suppose the objective of the study is to estimate how general drivers (owners of electric vehicles and gasoline-driven vehicles) view environment issues like Global Warming. Does the situation involve any response bias? Please provide a detailed and logical justification.

d) Suppose the objective of the study is to estimate how general drivers (owners of electric vehicles and gasoline-driven vehicles) view environment issues like Global Warming. Provide the description of the variable if you want the response to be in nominal scale of measurement.
