CHAPTER REVIEW PROBLEMS
6,33 An industrial sewing machine uses ball bearings that are tar-
geted to have a diameter of 0.75 inch. The lower and upper speci-
fication limits under which the ball bearings can operate are 0.74
inch and 0.76 inch, respectively. Past experience has indicated that
the actual diameter of the ball bearings is approximately normally
alty by the state office of consumer affairs. Bottles that have a net
content above 2.10 liters may cause excess spillage upon opening.
What proportion of the bottles will contain
a. between 1.90 and 2.0 liters?
b. between 1.90 and 2.10 liters?
c. below 1.90 liters or above 2.10 liters?
d. At least how much soft drink is contained in 99% of the bottles?
e. Ninety-nine percent of the bottles contain an amount that is
between which two values (symmetrically distributed) around
the mean?
distributed, with a mean of 0.753 inch and a standard deviation of
0.004 inch. What is the probability that a ball bearing is
a. between the target and the actual mean?
b. between the lower specification limit and the target?
c. above the upper specification limit?
d. below the lower specification limit?
e. Of all the ball bearings, 93% of the diameters are greater than
what value?
6.35 In an effort to reduce the number of bottles that contain less
than 1.90 liters, the bottler in Problem 6.34 sets the filling machine
so that the mean is 2.02 liters. Under these circumstances, what
6.34 The fill amount in 2-liter soft drink bottles is normally
distributed, with a mean of 2.0 liters and a standard deviation of
0.05 liter. If bottles contain less than 95% of the listed net content
