<h3>
Answers: Choice B and Choice C</h3>
========================================================
Explanation:
The symbol 
or mu represents the population mean, which is a parameter.
The symbol 
or sigma represents the population standard deviation, which is also a parameter. The same goes for the symbol p, without any hat on top, as it is the population proportion.
If something represents a population data item, then it's automatically a parameter. It might help to think both words "population" and "parameter" start with the letter P.
Based on those previous paragraphs, we can rule out choices A, D and E. Those three items are parameters. This leaves <u>choices B and C</u> as our final answers.
or xbar is a sample statistic, and it represents an estimate of the population mean. Similarly, 
or p-hat is the sample proportion and it represents an estimate of the population proportion. These are considered unbiased estimators.
Another example of an unbiased estimator is the variable s which represents the sample standard deviation and it estimates the value of sigma. All of these estimators have one thing in common: they are based on a sample, which in turn tries to predict what the corresponding population value is. In other words, the statistic's job is to estimate the parameter.
Below is a reference table for all of the items mentioned.

Answer:
to tell the truth and always be genuine
Explanation:
Baker, Schultz, and Halstead argue that the united states could exploit significant strategic and economic gains if it invests in cleaner energy technologies and supports international efforts to reduce carbon emissions.
The statement is false.
According to early projections from the US Energy Information Administration, cleaner renewable energy accounted for around 12.6% of total primary energy consumption and about 19.8% of domestically produced power in the US in 2020.
The policy, which was based on an economic model created by Resources for the Future, would cut carbon emissions by 50% by 2035.
The Council, which was established in 2017 by Ted Halstead, former Republican Secretaries of State James Baker and George Shultz, has put together a coalition of businesses, environmental organisations, economists, and other individuals to advocate their climate plan.
The complete question is:
Baker, schultz, and halstead argue that the united states could exploit significant strategic and economic gains if it invests in cleaner energy technologies and supports international efforts to reduce carbon emissions. True or false?
