95.44% IQ scores are between 77 and 125
We're given,
Mean (a)=101
standard deviation (b)=12
To find : ![P[77 < x < 125]](https://tex.z-dn.net/?f=P%5B77%20%3C%20x%20%3C%20125%5D)
Using Empirical Rule:
∴ 
![P[\frac{77-101}{12} < \frac{x-a}{b} < \frac{125-101}{12}]\\](https://tex.z-dn.net/?f=P%5B%5Cfrac%7B77-101%7D%7B12%7D%20%3C%20%5Cfrac%7Bx-a%7D%7Bb%7D%20%3C%20%5Cfrac%7B125-101%7D%7B12%7D%5D%5C%5C)
![=P[-2 < z < 2]\\](https://tex.z-dn.net/?f=%3DP%5B-2%20%3C%20z%20%3C%202%5D%5C%5C)
![=P[Z < 2]-P[Z < -2]\\](https://tex.z-dn.net/?f=%3DP%5BZ%20%3C%202%5D-P%5BZ%20%3C%20-2%5D%5C%5C)
=95.44% (approx)

Explanation:
The statement that is true of simon as an individual is; C: His annual deductible will be $800.
<h3>What is In-network Insurance?</h3>
For in - network insurance, we know the following facts;
- Charged a lower copayment rate after deductible.
- Incur a relatively low out-of-pocket amount.
- Have a relatively low annual deductible.
Now, in-network physicians help to reduce the cost of insurance to the individual and as a result, what is most likely going to happen is that Simon will have an annual deductible of $800 and is less likely that he will not pay anything after meeting this annual deductible.
The missing options are;
a. The cost of his annual physical will be 50% after deductible
b. The maximum amount that he can expect to pay out-of-pocket is $6,000.
c. His annual deductible will be $800.
d. Once he hits his annual deductible of $800, he will incur no additional costs for health care services for the rest of the calendar year.
