When bonding teeth, orthodontists must maintain a dry field. A new bonding adhesive called "Smartbond" has been developed to eliminate the necessity of a dry field. However, there is concern that the new bonding adhesive is not as strong as the current standard, a composite adhesive ( Trends in Biomaterials & Artificial Organs, Jan. 2003). Tests on a sample of 10 extracted teeth bonded with the new adhesive resulted in a mean breaking strength (after 24 h) of = 5.07 Mpa (megapascal). Orthodontists want to know if the true mean breaking strength of the new bonding adhesive is less than 5.70 MPa, the mean breaking strength of the composite adhesive. Conduct the appropriate analysis for the orthodontists at level a = 0.01 when: %3D (1) The standard deviation has been estimated to be s = 0.46 MPa; (2) the variance of the population distribution is known to be o? = 0.25 MPa.
