It is claimed that the data prove that stream 2 is cleaner than stream 1. An experimenter asked the following questions. When were the data taken? All in one day? On different days? Were the data taken during the same time period on both streams? Where the stream temperatures and flows the same? Where in the streams were the data taken? Why were these locations chosen? Are they representative? Are they comparable? Why do you think she asked these questions? Are there other questions she should have asked? Is there any set of answers to these questions (and others you invent) that would justify the use of a t test to draw conclusions? What conclusions?
