1. Binomial and normal distributions

Binomial distribution
-it is a discrete distribution
-every trial has only two possibilities - success or failure
-characterized by number of trials n and fraction of successes p
-example: the number of sixes in 30 rolls of a fair die is a binomial distribution. The number of heads in 15 tosses of a fair coin is also a binomial distribution

Normal distribution
-it is a continuous distribution
-every trial can result in any value for the variable
-characterized by mean mu and standard deviation sigma
-example: the distribution of men's heights in America is close to normal. ...

#### Solution Summary

This solution is comprised of a complete, neat and step-by-step explanation of the difference between the binomial distribution and normal distribution as well as the five steps of hypothesis testing.
