Instruction 8-5
The actual voltages of power packs labelled as 12 volts are as follows: 11.77, 11.90, 11.64, 11.84, 12.13, 11.99, and 11.77.
-Referring to Instruction 8-5,it is possible that the 99% confidence interval calculated from the data will not contain the mean voltage for the entire population.

Question

Quizplus · Accepted Answer

Since the sample size is relatively small (n=7), there is a possibility that the sample mean might not accurately represent the population mean. Additionally, the variation in the sample voltages suggests that there could be some variability in the population mean. Therefore, it is possible that the 99% confidence interval calculated from the sample data will not contain the mean voltage for the entire population.
