Assuming the population has an approximate normal distribution, if a sample of size n=20 has a sample mean bar{x}=15 and sample standard deviation s=3 What is the degree of freedom?

Question

Accepted Answer

Step:1 ：Given a sample size of ( n=20 )Step:2 ：Calculate the degree of freedom as ( n-1 )Step:3 ：Substitute the given value ( n=20 ) into the formulaStep:4 ：Degree of freedom ( = 20 - 1 )Step:5 ：Degree of freedom ( = 19 )Step:6 ：( boxed{19} )
