First find the slope between any two points:
Where
are the two points
So calculating the slope:
So the slope is
And our equation will be in the format of
where
and 
So, now we have half of the equation:
Now to calculate b, we can plug in a point
and solve for b.
So
Lets use the point
So:
And then:
So our final equation is
Where

Using the normal distribution, it is found that:
a) Her waist is at the 2.74th percentile.
b) 99.86% of female soldiers requires custom uniform pants.
<h3>Normal Probability Distribution</h3>The z-score of a measure X of a normally distributed variable with mean and standard deviation
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
.
Item a:
The percentile is the <u>p-value of Z when X = 26.1,</u> hence:
Z = -1.92
Z = -1.92 has a p-value 0.0274 = 2.74th percentile.
Item b:
The proportion is the <u>p-value of Z when X = 32 subtracted by the p-value of Z when X = 24</u>, hence:
X = 32:
Z = 3.
Z = 3 has a p-value 0.9987.
X = 24:
Z = -3.67.
Z = -3.67 has a p-value 0.0001.
0.9987 - 0.0001 = 0.9986 = 99.86% of female soldiers requires custom uniform pants.
