Test whether he given claim is supported or not supported using a 0.05 significance level. Assume that the sample has been randomly selected from a population with a normal distribution.

A manufacturer claims that the mean lifetime of its fluorescent bulbs is 1300 hours. A product tester selects 25 bulbs and finds the mean lifetime to be 1280 hours with a standard deviation of 80 hours. He claims that the mean lifetime is different from 1300 hours. Use a significance level of 0.05 to test whether the product tester's claim is supported or not supported.
