Current Attempt in Progress Let the sample size of the television tube brightness experiment be ten and the sample mean and sample standard deviation be 370.8 microamps and 18.2 microamps, respectively. Suppose that the design engineer claims that this tube will require at least 350 microamps of current to produce the desired brightness level. Choose an appropriate hypothesis to test. HO : M = i ,HI : M i Find the P-value for this test. O 0.0005
