58LEM 2 (15)nts ton). A medical manufacturer is evaluating a new epoxy hardener to replace the current ardener used in its production processes. The new hardener is manufactured by a slightly different process, so it needs be tested and compared to the current one. If no statistical difference in the means between the two processes is stablished, the new hardener will be accepted for production use. The first test being run in the study is a measurement of equilibrium moisture content. For each type of hardener, 40 different samples were measured for moisture content (in weight %) and were both determined to be approximately normally distributed. a) State a suitable null and alternative hypothesis for this situation. b) Compute the test statistic for your null hypothesis. c) Compute (or place a bound) on the p-value for your test outcome.
