The normal distribution is also known as the Gaussian
distribution and the “Bell-shaped curve”. Why is it also known by
these two names (hint – search for this on the internet). Under

Another type of distribution is the normal curve or sometimes
called the bell curve. If a distribution has a normal curve, it is
symmetrical with most of the probabilities located near the mean.
Many test scores are based on a bell curve. An example of a bell
curve is population IQ. The mean of the population is 100 with a
standard deviation of 15.

The weights of loads hauled by a trucking company approximately
follow a bell-shaped (normal) frequency curve with a mean of 15
thousand pounds and a standard deviation of 4 thousand pounds. Note
that: 15 ± (1)(4) ==> 11 to 19; 15 ± (2)(4) ==> 7 to 23; 15 ±
(3)(4) ==> 3 to 27 . According to the empirical rule,
approximately __________ percent of loads weigh between 3 thousand
pounds and 27 thousand pounds.

A particular population, for which the frequency curve is
bell-shaped (normal), has a mean of μ=100 and a standard deviation
of σ=18. For samples of size n=36 consider the sampling
distribution of the sample mean ("xbar").
Note that 18 36=3 and that
100±(1)(3)⟹97 to 103
100±(2)(3)⟹94 to 106
100±(3)(3)⟹91 to 109
According to the empirical rule, approximately _____
percent of samples of size 36 will produce a sample mean between 97
and 103.
