the pressure exerted on the floor by the heel of someone's shoe is inversely proportional to the square of the width of the heel

Katen [24]

P = k/w^2

first of all you need to find k 
But I kind of don't like the units of each value so let say 
400KPa = 4 * 10^5 Pa = 4 * 10^5 N/m^2 
2 cm = 2 * 10^-2 m 

input values in the equation 

4*10^5 = k/(4*10^-4) >>> k = 160 N 

P = 160/w^2 
it said if she wears a heel with a width of .5 cm 

P = 160(0.5 * 10^-2)^2 >>> P = 6400 KPa

The given sample's confidence interval is 4.73 ± 0.1199, or from 4.61 to 4.85

<h3>What is the z score?</h3>

The z-score is a numerical assessment of a value's connection to the mean of a set of values, expressed in terms of standards from the mean, that is used in statistics.

Given data;

Mean = 4.73

Standard deviation = 0.865

Sample size = 200

interval = 95%

Confidence interval=?

95% of samples contain the population mean (μ) within the confidence interval of 4.73 ± 0.1199.

Hence, the sample's confidence interval is 4.73 ± 0.1199, from 4.61 to 4.85

QveST [7]

Namely, what is 11.65 in percentage from 24.9

if we take 24.9 to be the 100%, let's see

$\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
24.9&100\\
11.65&x
\end{array}\implies \cfrac{24.9}{11.65}=\cfrac{100}{x}$

solve for "x".
