The change in air pressure when the pure tone is produced is mathematically given as
p(1/2000) =0 mP
<h3>What is the change in air pressure when the pure tone is produced?</h3>This pressure is referred to as the atmospheric pressure, air pressure, or simply pressure. It is the force that is exerted on a surface by the air that is above it due to the gravitational pull that gravity has on the surface. A barometer is an instrument most often used to measure the pressure of the atmosphere. When the pressure in the atmosphere changes, a column of mercury contained inside a glass tube in a barometer will either rise or sink.
Generally, the equation for is pressure mathematically given as
Therefore
p(1/2000) =2sin (4000\pi *1/2000)
p(1/2000) = 2sin (2\pi)
p(1/2000) = 2*0
p(1/2000) =0 mP
In conclusion, the pressure
p(1/2000) =0 mP

The question is incomplete. The complete question is :
The National Coffee Association reported that 62% of U.S. adults drink coffee daily. A random sample of 225 U.S. adults is selected. Round your answers to at least four decimal places as needed.
Required:
a. Find the mean μ.
b. Find the standard deviation σ.
c. The standard deviation σ.
Solution :
a). Percentage of the US adults who drinks coffee daily = 62%
Therefore, the mean, μ = 0.62
b). We know, p = μ = 0.62
And n = 225
Therefore, the standard deviation is given by :
c). Standard deviation, σ = 0.0324
