points A manufacturing company claims that  the average lifetime of their incandescent lamps is 1300 hours. A random sample of 16 lamps  are tested, and their lifetimes, in hours, are shown below: The company’s claim is considered valid if the computed t-value is between −t_0.025 and t_0.025   Assuming that the distribution of lifetimes is approximately normal, is the claim valid? Show  your solution and explain briefly
