Answer:
Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.
Explanation:
A confidence interval is a range of values, derived from the sample statistics, which may include the value of an unknown population parameter.
A 95% confidence interval indicates that between 152 of 160 samples (95%) of the same population will produce confidence intervals that will contain the population parameter.
It also means that we have a 95% confidence that the average (average amount) is among the resulting amounts obtained.
Logically, option "D" is missing the final part. This would be: D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $ 15.
This is the only true option, since the test is based on a sample of only 160 households, the entire population of households cannot be included.
Hence, the correct option is:
Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.

C.)intuitive listening takes place when the listener tries to discern the deeper meaning of a speaker’s words.
A.)Active
B.)efficient
Explanation:
Intuitive listening means that the person who is listening is trying to understand as well as imbibe what the other is saying to a deeper level.
This involves actively thinking about what the other person is saying and then critically discerning what it really means above the meaning of its own words.
Then the person who is listening reaches to the 'deeper' meaning or the essence of what the other person is trying to say.
This is the process that is involved in intuitive listening.
The potential GDP in the U.S. will be unaffected by the unemployment rate.
What is meant by potential GDP?
An estimation of the value of the output that the economy would have created if labor and capital had been engaged at their maximum sustainable rates—that is, rates consistent with steady growth and stable inflation—is known as potential GDP.
What is the unemployment rate?
The number of persons actively seeking work as a percentage of the labor force is used to calculate the unemployment rate in the United States. In July 2022, the US jobless rate dropped from 3.6% to 3.5%, the lowest level since February 2020, despite analysts' expectations that it would remain steady.
What causes a high unemployment rate?
Numerous factors, including those from the supply side—the worker—and the demand side—the employer—contribute to unemployment. High-interest rates, a worldwide recession, and a financial crisis could all have an impact on demand. Frictional unemployment and structural employment are major contributors on the supply side.
