Answer #1

Standard deviation is

\frac{B-A}{\sqrt{12}}

=\frac{40-35}{\sqrt{12}}

=\frac{ 5}{\sqrt{12}}

=1.44 ( A)

    The diameters of ball bearings made by a machine follow a normal distribution. Ball bearings that are too large or too small are undesirable since they will not work properly. The manager wants to see if the machine is producing ball bearings that are significantly different from .35 inches. To make sure the machine is working properly, we take a random sample of 25 ball bearings and find that the sample mean diameter is .34 inches. Assume the population standard...
