- A supplier claims that the true mean electrical resistance of wiring harnesses of a certain model is 30 ohms. A manufacturer that uses this harness wants to test whether this claim is true. Which of the following is the correct pair of hypotheses to use for this hypothesis test? Pick the right answer below by quoting the numbered point. 1. H0:μ=30 and H1:μ≠30 2. H0:μ⩾30 and H1:μ<30 3. H0:μ⩽30 and H1:μ>30 4. H0:μ≠30 and H1:μ=30 5. H0:μ<30 and H1:μ⩾30 6. H0:μ>30 and H1:μ⩽30% Calculate the value of t for the hypothesis test. (Give your answer correct to two decimal places.)
