Sample Mean:
The Sample Mean is the average mathematical value of a sample’s values. It is a statistical indicator used to analyze various variables over time. Statisticians and researchers obtain it by dividing the total sum of values of all data fragments and then dividing it by the total number of data sets.
Point Estimate:
p=x/
p is the point estimate for the population proportion, x is the number of
successes, n is the sample size
p= + /2
for the population proportion
x= + /2
for the population mean
= − /2
is the margin of error
