A soft drink bottler purchases glass bottles from a vendor. The bottles are required to have an internal pressure of at least
pounds per square inch (psi). A prospective bottle vendor claims that its production process yields bottles with a mean internal pressure of
psi and a standard deviation of
psi. The bottler strikes an agreement with the vendor that permits the bottler to sample from the production process to verify the claim. the bottler randomly selects
bottles from the last
produced, measures the internal pressure of each, and finds the mean pressure for the sample to be
psi below the process mean cited by the vendor. (a) Assuming that the vendor is correct in his claim, what is the probability of obtaining a sample mean this far or farther below the process mean?
(b) If the standard deviation were
psi as claimed, but the mean was
psi, what is the probability of obtaining a sample mean of
psi or below?
(c) If the process mean were
psi as claimed, but the standard deviation was
psi, what is the probability of obtaining a sample mean of
psi or below?
(b) If the standard deviation were
(c) If the process mean were
