2.  determine the mean & SD of the following data:  5, 7, 9, 12, 15, [show your calculations & formula; 6 points]

3.  Identify any outlier in the following data set:  5, 7, 8, 10, 20.  justify your answer by referring to the statistical test used to analyze the data, show any relevalent calculations, and its implications.  [2 points]

problems 4 - 5:  Clearly state the statistical test used, its p-value, and the implications of the p-value in regards to comparing the various experimental conditions, i.e. include a screen shot of the output of the program.
