For each of the following tests of hypotheses, determine whether the null hypotheses should be rejected. Use the classical method by finding the lower xL and upper xU limits for two-tail tests (or one of the two for a one-tail test). Additionally, don't forget to use a t-value (rather than a z-value) when n<30. A) Ho: µ = 6,000 Ha: µ ≠ 6,000; n = 70; x = 6,150; σ = 2,600; α = .01 B) Ho: µ = 50...
