Answer:
The standard error of the sample mean is _17.677_ psi.
Step-by-step explanation:
<u>Explanation</u>:-
A random sample of n = 8 specimens is collected.
Given sample size is n = 8
Given mean of the population 'μ' = 2500 psi
standard deviation 'σ' = 50 psi
Let x⁻ is the mean of the observed sample
Standard error of the sample mean = ...(i)
Given Population of standard error (S.D) 'σ' = 50 psi
Now substitute all values in (i)
<u>Conclusion</u>:-
The standard error of the sample mean is _17.677psi.
