Express the final answer to four decimal places e g.
													
																	A synthetic fiber used in manufacturing carpet has tensile. 
									
	
		
	
																	How is the standard deviation of the sample mean changed when the sample size is increased from n 6 to n 49. 
																	Find the probability that a random sample of n 6 fiber specimens will have a sample tensile strength that exceeds 75 75 psi. 
																	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. 
																	Find the probability that a random sample of n 6 fiber specimens will have sample mean tensile strength that exceeds 75 75 psi.
