The mean fineness, u, of yarn is expected to be greater than the standard value of 5 units. To test this claim, the factory graded 16 specimens of the yarn and found the sample average, x , to be 5.9 units. Assume that the measurement of fineness is normally distributed with a variance of o 2 = 4.0. Which can we state? Group of answer choices The P-value is P(Z21.8)=0.0359 and there is strong evidence that the mean exceeds 5 units. P(Z20.45)=0.3264 which indicates the data are consistent with a mean of 5. P(IZ|21.8)=0.0718 which does not constitute strong evidence against a mean. P(Z23.6)=0.0002 and there is strong evidence that the mean exceeds 5 units
