5. Brandon, a quality control engineer claims that the life length of a particular light bulb for an LCD projector follows an exponential distribution with B = 1000. Rodrigo obtains a random sample of the 10 light bulbs and places them on life test with the following results (measured in hours). (The data has been saved in the attached lifels.dat.) 613.10 3166.88 1685.59 226.15 107.29 530.62 1499.40 2732.40 1550.63 273.54 Use the appropriate test to determine whether Brandon's claim is correct, using both the critical value approach and p-value approach. (Use a = 0.05. Be sure to include all the steps!)
