hammer [34]

Answer: The raw score for Daniel's exam grade is 101.69.

Step-by-step explanation:

For x be any random variable.

Formula for z-score :

$z=\dfrac{x-\mu}{\sigma}$ , where $\mu$ = population mean

$\sigma$ = population standard deviation.

Let x be the raw score for Daniel's exam grade.

As per given , we have

$\mu=90$ , $\sigma=7$ and z= 1.67 , put these values in the above formula , we get

$1.67=\dfrac{x-90}{7}\\\\\Rightarrow\ x-90=7(1.67)=11.69\\\\\Righarrow\ x=11.69+90=101.69$

Hence, the raw score for Daniel's exam grade is 101.69.
