Problem 9.071 Let the sample size of the television tube brightness experiment be ten and the sample mean and sample standard deviation be 262.0 microamps and 10.9 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. Choose an appropriate hypothesis to test. Ho:= H1H # Find the P-value for this test. 0.0025 < P-value < 0.0050 0.025 < P-value < 0.050 0.25 P-value <0.50 0.0005 P-value < 0.0010 With a significance level of x = 0.05, fail to reject Ho OR reject For this test, we assumed that the underlying distribution of the data is a t-distribution.
