At a computer manufacturing company, the actual size
of a particular type of computer
chips is normally distributed with a mean of 2 centimeters and a
standard deviation of 0.2
centimeter. A random sample of 14 computer chips is taken.
a. What is the probability that the sample mean will be between
1.99 and 2.01
centimeters?
b. What is the probability that the sample mean will be below 1.95
centimeters?
c. Above what value do 2.5% of the sample means fall?

A local company makes snack-size bags of potato chips. The
company produces batches of 400 snack-size bags using a process
designed to fill each bag with an average of 2 ounces of potato
chips. However, due to imperfect technology, the actual amount
placed in a given bag varies. Assume the population of filling
weights is normally distributed with a standard deviation of 0.1
ounce. The company periodically weighs samples of 10 bags to ensure
the proper filling process. The last...

The heights of 1000 students are approximately normally
distributed with a mean of 174.5 centimeters and a standard
deviation of 6.9 centimeters. Suppose 200 random samples of size 25
are drawn from this population and the means recorded to the
nearest tenth of a centimeter. Determine (a) the mean and standard
deviation of the sampling distribution of X¯; (b) the number of
sample means that fall between 171 and 177 cm.

The heights of 500,000 students are approximately normally
distributed with a mean of 174.5 centimeters and a standard
deviation of 6.9 centimeters. If 200 random samples of size 25 each
are drawn from this population and the means are recorded to the
nearest tenth of a centimeter,

175.85 centimeters inclusive;
2.Determine how many sample means falls below 171.95
centimeters.
