Answer:
B) The probability is 0.95 that the difference in sample means for miles traveled by the two companies is between 1.86 miles and 2.15 miles.
Explanation:
The samples are being used to find a difference in the population of the means.
A differential in sample averages of miles traveled more by two companies is between 1.86 and 2.15 miles, as per our 95 percent confidence level.
Confidence level:
- To begin with, a confidence interval is a tool for forecasting or estimating a population proportion rather than a sample statistic.
- The confidence interval is calculated using sample statistics.
- Moreover, its confidence level denotes how confident one can be about the confidence level, as the name implies.
Therefore, the final answer is "Option A".
