Let the sample size of the television tube brightness experiment be 10 and the sample mean and sample standard deviation be 262.6 microamps and 11.3 microamps, respectively. suppose that the design engineer claims that this tube will require at least 250 microamps of current to produce the desired brightness level. formulate and test an appropriate hypothesis to confirm this claim using
α=0.05.find the p-value for this test. state any necessary assumptions about the underlying distribution of the data.
