Find the mean, sample standard deviation–treating the data as a
sample, and the population standard deviation–treating the data as
a population.

Consider a sample with 10 observations of –1, 1, 0, 14, –2, 11,
9, 12, 5, and 2. Use z-scores to determine if there are
any outliers in the data; assume a bell-shaped distribution.
(Round your answers to 2 decimal places. Negative values
should be indicated by a minus sign.)
The z-score for the smallest observation
