2. Explain which of the three values (mean, median, mode) is the best representation of central tendency for this specific problem.Do not give a general answer about what the mean, median, or mode is.The question is designed to see if you can pick which one of these measures of central tendency fits the data the best.
3. What is the standard deviation for the number of hours worked? Does the standard deviation support that the data is clumped together or spread apart?Justify your answer, and make sure the range is mentioned in this justification.
