Unformatted text preview: nown how they locate their winter homes. One possibility is that they possess some magnetic material that could be utilized in a magnetic field. A biologist wished to determine whether monarchs have some magnetic material in their bodies, using extremely sensitive magnetometers. Unfortunately the magnetometer itself creates some background magnetism, about 200 pico
emus of magnetic intensity. (A pico
emu is 10−12 electromagnetic units.) In order to demonstrate that monarchs have some magnetic material in their bodies, it must be shown that their mean magnetic intensity exceeds 200 pico
emus naturally. For this test we will use a 5% level of significance. Step 1: Determine the Hypotheses The null hypothesis states that the population mean is equal to a specific value: !! :µ = ! The alternative hypothesis is one of the following inequ...
