Normal probability distribution because the area under the curve = 1 and the curve is symmetrical, we can say the probability of getting more than 78 % is 0.5, as is the probability of getting less than 78 % to define other probabilities (ie.
Where ¯ and are the mean and size of sample respectively.
The sample is randomly drawn from the source population. ¯ = = ¯ =. The weighted arithmetic mean (or weighted average) is used if one wants to combine average values from different sized samples of the same population: The sample is randomly drawn from the source population.
