... An Example (See pg. 60) • Consider an investigation into the formulation of a new “synthetic” fiber that will be used to make cloth for shirts • The response variable is tensile strength • The experimenter wants to determine the “best” level of cotton (in wt %) to combine with the synthetics • Cott ...

... All of the hypothesis tests we have done before have involved means and differences of means, but hypothesis testing can be applied to any type of distribution. In this next section we will look at how it can be used to compare differences in population proportions. As before we want to see if there ...
