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.

Explanation:
Currently consumers of vodka were levied tax of $2. However, government decided to provide tax relief to consumers and shift the burden on producer. There will be no change in the well being of consumers and producers.
Tax is a cost that shifts demand curve if consumers pay tax. Supply curve shifts if producers pay tax. The overall effect, however remains the same. If producers pay tax, cost per unit vodka will increase which will be reflected increased prices. Similarly, if consumers pay tax, they will demand lesser. so there is no change overall.
