I suspect you want the area under the standard normal curve to the left of z = -0.95.
On my calculator I typed in normal cdf(-100, -0.95) and got the result 0.171.
To determine the thickness of the film, we assume the shape of the film is in a form of cylinder where the thickness is equal to the height. The volume of a cylinder is expressed as:
V = pi (r^2) h
We calculate as follows:
0.23 = pi (10^2) (h)
h = 0.0007 cm
Answer:100$-100% 100*12.5=1250
1250/100=12.5
?-12.5%
