Answer:
The sample proportion, denoted by ^p, is given by the formula ^p= [tex]\frac{x}{n}[/tex], where x is the number of individuals with a specified characteristic in a sample of n individuals.
Step-by-step explanation:
Sample proportion is used to determine sample mean, sample standard error and test the hypotheses about the population.
sample mean can be stated as p and sample standard error can be found using the equation[tex]\sqrt{\frac{p*(1-p)}{n} }[/tex] where
And if n×p×(1-p)≥10, then sample is assumed large enough to assume normal distribution and apply statistical test.
