Two methods for precisely estimating the weights of very large objects are being evaluated for consistency. From 9 measurements using method 1, there is a variance of 1.023; from 14 measurements using method 2, there is a variance of 0.095. Does method 1 appear to have more variability than method 2? Select the appropriate critical value (CV), test statistic (TS), and decision and state the null hypothesis. (Useα= 0.05).
◦
CV = 5.049; TS = 10.7684; rejectH0: The difference between methods is not statistically significant.
◦
CV = 6.287; TS = 115.9589; rejectH0: The difference between methods is not statistically significant.
◦
CV = 5.049; TS = 10.7684; fail to rejectH0: The difference between methods is statistically significant.
