Evaluate the formula z equals Start Fraction x overbar minus mu Over Start Fraction sigma Over Start Root n End Root End Fraction End Fraction z= x−μ σ n when mu μ equals = 118, n = 22, x overbar x equals = 123, and sigma σ equals = 2 2. z = nothing (Round to three decimal places as needed.)
Homework Answers
Solution :
=
118
= 123
= 2.2
n = 22
Using z-score formula,
z = (
- 
) /
/ 
n
z = (123 - 118) / 2.2 /
22
z = 10.660
