Mean = 100, standard deviation = 25, what is the probability from 75 to everything less (that is, P(X < 75)? Is
this a regular normal distribution problem or an unusual normal distribution problem?
REGULAR NORMAL DISTRIBUTION PROBLEM.
Z = ( X )/ = (75-100

MOST USED STATISTICS:
The average is typically called the mean in statistical analysis, and it is a measure
of the central tendency of the numbers. The standard deviation is a measure of
how the numbers spread out. In mos
The factorial of a non-negative integer n, denoted by n!, is the product of all positive
integers less than or equal to n. For example,
4! = 4 X 3 X 2 X 1
The value of 0! is 1, according to the convention for an empty product.
