Question

Suppose that a laboratory analyzes biological specimens to determine the concentration of toxins. The laboratory analyzes
each specimen five times and reports the mean results. The five measurements for a given specimen are not all equal, but the
results follow a normal distribution almost exactly. Assume the mean of the population of all repeated measurements, pu, is the
true concentration in the specimen. The standard deviation of this distribution is known to be 0.1750 ppm.
One of the laboratory's technicians evaluates the claim that the concentration of toxins in a single specimen is at most
7.500 ppm using a one-sample z-test for a mean. The true concentration is the mean, µ, of the population of
repeated analyses.
Ho: H = 7.500 ppm
H 1: µ > 7.500 ppm

Alison learns that sea creatures sell for a mean of u = 3,345 bells with a standard deviation of o = 3,684 bells ("bells" is the currency in the game).
