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)

The angle formed between the line of pull of a muscle and the longitudinal axis of the bone in which the muscle is acting. The line of pull is usually indicated by the joint angle. It affects the strength of muscle action; at only certain angles of pull can a muscle exert maximal tension.
The given statement about the correlation between two variables is; False
<h3>Pearson's correlation coefficient </h3>
Pearson's correlation coefficient is the measure of linear correlation between two sets of data.
Pearson's r is always between the values of -1 and +1.
In that range, -1 denotes a perfect negative while +1 denotes a perfect positive relationship and 0 denotes the perfect absence of a relationship.
Finally, Pearson's r is symmetric and as such the correlation between two variables x and y must be the same as the correlation between y and x.
Thus, if the correlation between x and y is 0.8, then the correlation between y and x must be also 0.8 and not -0.8 as the question states.
