The Bootstrap tool constructs sampling distributions for the following statistics:
(1)Mean
(2)Median
(3)Standard deviation
(4)Variance
(5)Skewness
(6)Kurtosis
(7)Coefficient of variability
(8)Mean standard error
(9)Range minimum (multiple-simulation method only)
(10)Range maximum (multiple-simulation method only)
(11)Range width (multiple-simulation method only)

?
______________
What is the standard deviation?
______________
Find the probability that
exceeds 116.

One application of seasonal indexes is to remove the seasonal variation in a time series.The process is called deseasonalizing,and the result is called a seasonally adjusted time series.
