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.
