Answer:
We are 95% sure that the true difference in time to pack the jars between the old machine and the new machine is between 3.08 and 10.12 minutes, that is, we are 95% sure that the new machine takes between 3.08 and 10.12 minutes less than the old machine to pack the jars.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
95% confidence interval of (3.08, 10.12) for the true difference in average times to pack the jars (old machine - new machine).
We are 95% sure that the true difference in time to pack the jars between the old machine and the new machine is between 3.08 and 10.12 minutes, that is, we are 95% sure that the new machine takes between 3.08 and 10.12 minutes less than the old machine to pack the jars.
