Question
Consider the accompanying data on breaking load (kg/25 mm width) for various fabrics in both an unabraded condition and an abraded condition. Use the paired f test to test H_0:mu_D = 0 versus H_ a:mu_ D > 0 at significance level 0.01. (Use mu_ D = mu_ U - mu_ A) Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.) t = 1.8465 P-value = 0.05413 State the conclusion in the problem context. Fail to reject H_0. The data does not suggest a significant mean difference in breaking load for the two fabric load conditions. Reject H_0. The data does not suggest a significant mean difference in breaking load for the two fabric load conditions. Reject H_0. The data suggests a significant mean difference in breaking load for the two fabric load conditions. Fail to reject H_0. The data suggests a significant mean difference in breaking load for the two fabric load conditions.Explanation / Answer
from above t =1.7265
and p value =0.064
please revert
