The manufacturer of Riordan Metal claims the average force required to break a 5 mm diameter rod of its special alloy is 500 N. To test this claim, 25 rods are stressed, with the sample mean (x) and sample standard deviation (s) of the forces required to break these rods being 480 N and 55 N, respectively. Using the T test, determine the probability of this occurring.

Problem 7.17 A cylindrical specimen of some metal alloy 11.0 mm (0.4331 in.) in diameter is stressed elastically in tension. A force of 14300 N (3215 lbf) produces a reduction in specimen diameter of 7 × 10-3 mm (2.756 × 10-4 in.). Compute Poisson's ratio for this material if its elastic modulus is 100 GPa (14.5 × 106 psi).

A cigarette manufacturer claims that the average nicotine content of their new brand XXX is at most 1.35 mg. It would be unwise to reject the manufacturer's claim without strong contradictory evidence. An appropriate problem formulation is to test A random sample of 100 brand XXX cigarettes are tested and the sample standard deviation and sample mean are found to be 0.07 mg and 1.361 mg, respectively. Assuming the central limit theorem applies and s ≈ σ, find the p-value...

6.3.7 A manufacturer wants to assess whether or not rods are being constructed appro- priately, where the diameter of the rods is supposed to be 1.0 cm and the variation in the diameters is known to be distributed Nu, 0.1). The manufacturer is willing to tolerate a deviation of the population mean from this value of no more than 0.1 cm, i.e., if the population mean is within the interval 1.0 +0.1 cm, then...
