![### IQ Distribution and Mensa Membership Qualification
#### MENSA Membership Criteria
(d) **MENSA** is an organization whose members have the top 2% of all IQs. Find the minimum IQ needed to qualify for the MENSA organization.
\[ \text{Minimum IQ:} \space \underline{\hspace{2cm}} \]
#### Probability and IQ Distribution Graph
(e) **Sketch the graph, and write the probability statement.**
Below, you should provide a graph that illustrates the normal distribution of IQ scores, with the top 2% highlighted to represent the MENSA qualification threshold.
Additionally, include the appropriate probability statement indicating the IQ value \( X \) that corresponds to this threshold.
#### Middle 50% IQ Range
(f) **The middle 50% of IQs fall between what two values?**
\[ \underline{\hspace{4cm}} \space - \space \underline{\hspace{4cm}} \]
In this section, determine the IQ range that contains the middle 50% of the population, which corresponds to the interquartile range (IQR).
**Note:** Please note that specific calculations and detailed illustrations are necessary to complete sections (d) and (f), which typically involve the use of statistical tools and knowledge of normal distribution properties.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F72f09de3-af56-4252-96e1-7fcdd8b83667%2F97f71f42-bcee-4fc2-92df-64860d87bd69%2F4v2j17i_processed.png&w=3840&q=75)
