"An electronic manufacturer is investigating a new amplifier, which the company claims has a mean amplification factor of 27 dB with a standard deviation of 3.5 dB. A batch is being accepted, if the mean of a random sample of 12 specimens falls above 27.5 dB. What is the chance for the batch to be accepted (beta) for the case where the true population amplifying factor is 26.65 dB."

A manufacturer of electronic kits has found that the mean time required for novices to assemble its new circuit tester is 3.1 hours, with a standard deviation of 0.6 hours. A consultant has developed a new instructional booklet intended to reduce the time an inexperienced kit builder will need to assemble the device and the manufacturer needs to decide whether or not to send out the new booklet. The testable hypotheses in this situation are ?0:?=3.1H0:μ=3.1 vs ??:?<3.1HA:μ<3.1. 1. Identify...
