Tensile Strength Tensile Strength is the amount of stress a material can withstand before it breaks. Researchers wanted to determine the tensile strength of a resin cement used in bonding crowns to teeth. The researchers bonded crowns to 72 extracted teeth. Using a tensile resistance test, they found the mean tensile strength of the resin cement to be 242.2 newtons (N), with a standard deviation of 70.6 N. Based on this information, construct a 90% confidence interval for the mean tensile strength of the resin cement.
