I have only one blank sheet of paper to use for scratch paper. I understand that this is the only piece of paper that I am allowed to write on during the exam. I have shown the camera the front and back of my scratch page. Note: Failure to adequately meet this requirement will result in disqualification of your test score and you will be required to take a cumulative exam over the course material, on campus, in order to determine if you pass.

A local environmental group is concerned about increasing mineral content near a new manufacturing facility. Three years ago the silica content in a local river was determined to be 23 mg/L (in the range of 5 to 25 mg/L commonly found in natural waters). Recently, 6 samples were taken which had an average of 26 mg/L and standard deviation of 1.6 mg/L. An hypothesis test is to be performed to see if, with a confidence level of 90%, the silica level has increased. For this hypotheses test, the t critical value which the test statistic should be compared to is
