The three data sets presented below have the same MEAN and
RANGE. Assume that these data were obtained from samples.
Data Set A: 5, 7, 9, 11, 13, 15, 17.
Data Set B: 5, 6, 7, 11, 15, 16, 17.
Data Set C: 5, 5, 5, 11, 17, 17, 17.
What sample parameter will you use to differentiate among them?
Support your answer by computing the value of this parameter for
each of these sample data sets.

Suppose random samples of the same size are taken from two
different populations with the same mean but different standard
deviations. If you make two confidence intervals, one from each
sample, and these intervals have the same confidence level, how
will the confidence intervals differ? Explain.
