Question:
35. A sample of 14 joint specimens of a particular type gave a sample mean proportional limit stress of 8.48 MPa and a sample standard deviation of .79 MPa
( Characterization of Bearing Strength Factors in Pegged Timber Connections, J. Struct. Engrg., 1997: 326—332).
a. Calculate and interpret a 95% lower con dence bound for the true average proportional limit stress of all such joints. What, if any, assumptions did you make about the distribution of proportional limit stress?
b. Calculate and interpret a 95% lower prediction bound for the proportional limit stress of a single joint of this type.
