Suppose there are n observations in a data set consisting of the observations x1, x2, x3, ..., xn.
Rounding rule: round to one more decimal place than the highest number of decimal places contained in the data.
The formula can also be represented as sigma * xi / n.
x bar = SAMPLE MEAN
Mu = POPULATION MEAN
n= sample size
N= POPULATION SIZE
The sum of the deviations from the mean is always equal to 0.
The mean will always be pulled towards any outliers.
Ex: the average price of similar televisions at different stores. This is quantitative data that does not have outliers since the TVs at the different stores are similar
The answer is 5/8.which is half of the cup of rasins.
