Question

You take a random sample of 50 IQ netbooks from Aver Electronics, and find that the average battery life of the sample is 370 hours. Does this mean that the IQ's battery life is less than 400 hours, on average?

Answer 1

Yes 370 < 400 this means given your sample which has an avg. of 370h of battery life does not exceed the avg. of another sample or expected value of an avg. 400h.

Hope this helps.
