Consider a normal population with mu = 25 and sigma = 7.0.
(A) Calculate the standard score for a value x of 26
(B) Calculate the standard score for a randomly selected sample of 30 with = 26
(C) Explain why the standard scores of 26 are different between A and B above
** Please see the attached file for the complete solution response **
(A) Calculate the standard score for a value x of 26.
Given that µ = 25, σ = 7, X = 26
Therefore, standard score, (see attached for equation) …
The solution provides step by step method for the calculation of standard scores. Formula for the calculation and Interpretations of the results are also included.
