Answer:

=NORM.INV(0.17,98,15)

Step-by-step explanation:

Consider X represents the IQs of sample participants.

Then X follows the Normal Distribution with mean 98 and standard deviation 15.

That is,

$X \sim N(98,15)$

The probability value is 17th percentile (that is 0.17)

To find the value of X using Excel, the<em> Inverse Normal Distribution </em>is used.

The Excel function =NORM.INV(0.22,105,17) is used to find the IQs of sample participants.

Use the Normal model ​N(98​,15) for the IQs of sample participants. What IQ represents the 17th percentile? Use the appropriate
