The grades on a history midterm at Santa Rita are roughly symmetric with u == 76 and o = 3.0. Ben scored 71 on the exam. Find the z-score for Ben's exam grade. Round to two decimal places.

Respuesta :

Ц = 76

σ = 3.0

x= 71

The formula is given by;

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

substitute the values into the formula;

[tex]Z=\frac{71-76}{3.0}[/tex]

[tex]Z=-\frac{5}{3}[/tex]

Z= - 1.67
