Use only Table V of Appendix A.
(a) Do the data suggest that the two methods provide the same mean value for natural vibration frequency? Find interval for P-value:
i
< P-value <
Conclusion: For a significance level of a = 0.05, we would
the null hypothesis. There
sufficient
evidence to conclude that the two methods provide different mean values for natural vibration frequency.
(b) Find a 95% confidence interval on the mean difference between the two methods and use it to answer the question in part (a).
Round your answer to 3 decimal places.
≤ MD ≤
i
Conclusion: Does the confidence interval indicate that the two methods provide different mean values for natural vibration
frequency?
