Seven identical model truss bridges are constructed. Each is loaded with increasing masses until it collapses. The masses used are in 50g increments. The loads at failure are 1.40 kg, 1.40 kg, 1.45 kg, 1.50 kg, 1.55 kg, 1.60 kg, and 1.60 kg. If an additional truss is constructed, estimate with 95 % confidence the loaded mass at which the truss will fail.
