A synthetic fiber used in manufacturing carpet has tensile strength that is normally distributed with mean 75.5 psi and standard deviation 5.5 psi. How is the standard error of the mean changed when the sample size is increased from n = 10, to n = 20? Would a change in the value of the mean affect the standard error? Explain and include you solution. O a. Standard Error of the mean increases as the sample size increases O b. The value of the mean does not change the standard error of the mean O c. NONE O d. Standard Error of the mean decreases as the sample size increases. The value of the mean does not change the standard error
