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
