A random sample of 100 teachers in a large metropolitan area revealed a mean weekly salary of $487 with a standard deviation of $48. With what degree of confidence can we assert the average weekly salary of all teachers in the metropolitan area is between $472 and $502?

I can't figure out how to calculate the degree of confidence, i.e. Z alpha over 2...anyone good with statistics?

When light bulbs were invented during the turn of the century, it was so durable it could last a lifetime. But manufacturer later figured out it will not be a sound business idea to make bulbs to last a lifetime, since they will incur no re-orders.

So, they had to put a shelf life to bulb to ensure cycles of repeat orders. A sound business idea.
