Question Completion Status: QUESTION 1 What is the z-score for a data value equal to 45, if the mean is 40 and the standard deviation is 107 Oz.5 Oz=1.5 Oz-0.5 z= -1.5 QUESTION 2

Answer 1

$\mathbf{Solution}$

$\mathbf{given:}\;score\;(X)=45,\;mean\;(\mu)=40,\;standard\;deviation\;(\sigma)=10$

$\mathbf{formula:}\;\mathbf{z}=\frac{X-\mu}{\sigma}$

$\mathbf{z}=\frac{45-40}{10}$

$\mathbf{z}=\frac{5}{10}$

$\mathbf{z}=\mathbf{{\color{Red} 0.5}}$
