About 2.5% of the women have a body temperature more than 2 standard deviations above the mean.
<h3>What is the
empirical rule?</h3>
Empirical rule states that for a normal distribution, about 68% of the values fall within one standard deviation from the mean, 95% of the values fall within two standard deviation from the mean and 99.7% of the values fall within three standard deviation from the mean.
Amount that have more than 2 standard deviations above the mean = (100% - 95%) / 2 = 2.5%

The Area of the fabric required is 3.6 square feet
The square's side length is 3 feet.
Due to the fact that Lin is creating a window covering for a window that is half circle-shaped on top of a square.
The window covering must therefore be a semicircle with a 3-feet diameter.
thus the semicircle's radius is equal to d/2 = 3/2 feet
Now, the Area of the semicircle,
Putting the value of the radius in the equation, we have,
Hence, The Area of the fabric required = 3.6 square feet
