A synthetic fiber used in manufacturing carpet has tensile strength that is normally distributed with mean 75.5 psi and standard deviation 3.5 psi. How is the standard deviation of the sample mean changed when the sample size is increased from n equals 9 to n equals 45 ? Round all intermediate calculations to four decimal places (e. g. 12.3456) and round the final answer to three decimal places (e. g. 98.768). The standard deviation is by psi.
