... (c) Standard Deviation is s = √s2 = √ (0.227125) = 0.4765 (d) xbar + 2 s = 2.024 ; xbar – 2s = 0.118; At least 95% of observation values lie within this range of 0.118 and 2.024. This conforms to the Empirical Rule which states that at least 95 % of the number of observations will lie within the ran ...

Sampling
... Central Limit Theorem, which states that the sampling distribution of the mean will be normally distributed as the sample size (n) increases, even if the population distribution is not normally distributed. • This means that when we choose samples of the same size from the universe (e.g. retail outl ...

... We will NOT include computations for the mode because there are none. You just identify the group with the highest frequency, There are two types of equations for each measure: 1) Parametric measure. This is the real value or parameter of the population. 2) Sample measure. This is an estimate of the ...
