Step-by-step explanation:
Answer:
sxbar=s/sqrt(n)
Standard error
Step-by-step explanation:
If population standard deviation is not known, then the sample estimate of standard deviation is used which is denoted by s. The standard deviation of the sample is calculated as an estimate. The population standard deviation of xbar is sigmabar which is computed as
σxbar=σ/sqrt(n)
If the population standard deviation is unknown, then standard deviation of xbar is computed as
sxbar=s/sqrt(n).
It is also known as standard error.
