The Central Limit Theorem states that
a) When the population distribution is
normal the sampling distribution will also
be normal
There are many distribution curves but
only one standard normal curve.

when n is sufficiently large ( 30), the
sampling distribution of is approximately
normal even if the population distribution
is not normal

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
