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.
