Extracted text: 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 16 light bulbs. If the t-value falls between - to 9g and to go- then the company will be satisfied that it is manufacturing acceptable light bulbs. For a random sample, the mean life span of the sample is 1015 hours and the standard deviation is 26 hours. Assume that life spans are approximately normally distributed. Is the company making acceptable light bulbs? Explain. The company V making acceptable light bulbs because the t-value for the sample is t= and to on =. (Round to two decimal places as needed.)
