A company manufactures light bulbs. The company wants the bulbs to have a mean life span of 1010 hours. This average is maintained by periodically testing random samples of 25 light bulbs. If thet-value falls between t0.99 and t0.99, then the company will be satisfied that it is manufacturing acceptable light bulbs. For a randomsample, the mean life span of the sample is 1016 hours and the standard deviation is 27 hours. Assume that life spans are approximately normally distributed. Is the company making acceptable lightbulbs? Explain.

The company

making acceptable light bulbs because thet-value for the sample is t=

nothing

and t0.99=

nothing

.

(Round to two decimal places asneeded.)
