Normal Distribution is _____________.

Z-Score is used to check how many standard deviations away from the mean, a _________________lies.

Which of the following are the Terminologies of Probability?

Bernoulli Trials have _________ outcomes.

The Binomial distribution is the Probability distribution of the number of successes in _________Bernoulli trials.

Probability Density Function is the Probability distribution of a ____________ random variable.

The area under a probability density function gives the probability for the __________ variable to be in that range.

Taking __________ samples of equal size from the data, the sample means are approximately normally distributed.

In a normal distribution the ________________.

Normal distribution with a mean _____ and a standard deviation of ____ is called a Standard Normal Distribution.

Central Limit Theorem states that:

If we take means of random samples from a distribution and we plot the means, the graph approaches to a ___________distribution when we have taken a sufficiently large number of such samples.

The Central Limit Theorem also states that the mean of __________ means is approximately equal to the mean of __________means.

A positive Z score indicates that the observed value is Z standard deviations __________ mean.

______% of data lies within 1 standard deviation of the mean
______% of data lies within 2 standard deviations of the mean
______% of data lies within 3 standard deviations of the mean
