In the book Design and Analysis of Experiments, 8th edition (2012, John Wiley & Sons), the results of an experiment involving a storage battery used in the launching mechanism of a shoulder-fired ground-to-air missile were presented. Three material types can be used to make the battery plates. The objective is to design a battery that is relatively unaffected by the ambient temperature. The output response from the battery is effective life in hours. Three temperature levels are selected, and a factorial experiment with four replicates is run. The data are as follows:
(a) Test the appropriate hypotheses and draw conclusions using the analysis of variance with ◊α◊◊◊◊◊◊◊
(b) Graphically analyze the interaction.
(c) Analyze the residuals from this experiment.
Week 2: • Activity along mid-ocean ridges: o Deep ocean environments exist where ridges of tectonic plates exist § Newly made rock continuously being regenerated from magma underneath, solidified immediately by cold water § Geologic, seismic environments § “Chimneys” of rock form and release heat, smoke, toxic materials, etc. o Abundant oasis of life along black smokers: huge temperature gradient § How does life survive within such a temperature gradient • The sea floor: summary o Earth exists as layers with differe nt densities
