Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

The probability that a randomly selected customer of the Federal Bank will use their e-bank account for
their next transaction is 0.45. Consider a random sample of 5 customers. Let R be the number of these 5
customers who will use their e-bank account for their next transaction. Assume that R is a binomial
random variable.
Find the probability that 3 of the customers in this sample will use their e-bank account for their
next transaction.
