Solution
Arithmetic mean: often referred to as simply the mean or average when the context
is clear, is a method to derive the central tendency of a sample space. ---------------------------------
--------------------------------------------------------------------- Mode : is the value that occurs most
frequently in a data set or a probability distribution -------------------------------------------------------
----------------------------------------------- sample variance: is the natural measure of the center of
the random sample. --------------------------------------------------------------------------------------------
---------- null hypothesis: typically corresponds to a general or default position. -------------------
----------------------------------------------------------------------------------- median: is described as
the numerical value separating the higher half of a sample, a population, or a probability
distribution, from the lower half. ----------------------------------------------------------------------------
-------------------------- alternative hypothesis: is a statement of what a statistical hypothesis test
is set up to establish. ------------------------------------------------------------------------------------------
------------ range: the difference between the highest and the lowest values in a set ----------------
-------------------------------------------------------------------------------------- standard normal
distribution: is a normal distribution with zero mean ( mu=0 ) and unit variance ( sigma^2=1 )
