3. Light Bulb Manufacturing A company manufactures light bulbs. The company
wants the bulbs to have a mean life span of 1000 hours. This average is
maintained by periodically testing random samples of 16 light bulbs. If the
t-value falls between a 99% confidence interval, the company will be satisfied
that it is manufacturing acceptable light bulbs, A sample of 16 light bulbs is
randomly selected and tested. The mean life span of the sample is 1015 hours
and the standard deviation is 25 hours. Assume the life spans are
