Is there strong evidence that the statement of the quality inspector is true? Use ?=0.05 Find the: Parameter of interest: ? Null hypothesis: ? Alternative hypothesis: ? Test statistic: ? Reject H0 if: ? Computations: ? Conclusion: ?(i) State the hypotheses, identify the claim with the correct hypothesis, and determine whether it is a one-tailed or two-tailed test. (ii) Find the P-value. Round the answer to at least four decimal places. (iii) Make the decision and summarize the results.A supplier claims that the true mean electrical resistance of wiring harnesses of a certain model is 30 ohms.
