1.3 A certain polymer is used for evacuation systems
\nfor aircraft. It is important that the polymer be resistant
\nto the aging process. Twenty specimens of the
\npolymer were used in an experiment. Ten were assigned
\nrandomly to be exposed to an accelerated batch
\naging process that involved exposure to high temperatures
\nfor 10 days. Measurements of tensile strength of
\nthe specimens were made, and the following data were
\nrecorded on tensile strength in psi:
\nNo aging: 227 222 218 217 225
\n218 216 229 228 221
\nAging: 219 214 215 211 209
\n218 203 204 201 205
\n(a) Do a dot plot of the data.
\n(b) From your plot, does it appear as if the aging process
\nhas had an effect on the tensile strength of this polymer? Explain.
\n(c) Calculate the sample mean tensile strength of the
\ntwo samples.
\n(d) Calculate the median for both. Discuss the similarity
\nor lack of similarity between the mean and
\nmedian of each group.<\/p>\n
