REVIEW – APPLICATIONS OF THE NORMAL DISTRIBUTION

2
What is the mean and standard deviation of a Standard Normal Distribution? Why do we need a Standard Normal Distribution? The Standard Normal Distribution

3
The life span of domesticated cats is normally distributed with a mean of 15.7 years and a standard deviation of 1.6 years. What is the probability that a cat will live to be older than 16 years? Finding Probabilities

4
The life span of domesticated cats is normally distributed with a mean of 15.7 years and a standard deviation of 1.6 years. How old would a cat have to be for it to be in the top 10% of cat ages? Finding Values

5
The life span of domesticated cats is normally distributed with a mean of 15.7 years and a standard deviation of 1.6 years. If we sampled 9 cats, what is the probability that their mean age would exceed 16 years? The Central Limit Theorem

6
The average number of cats “singing” outside my window every night is 4. What is the probability that on a randomly selected night, there will be 5 cats “singing”? The Binomial and Poisson Distributions

7
In the US, about 63% of all domesticated cats have been “de-clawed”. In a random sample of 320 cats, what is the probability that at least 200 have been declawed? Normal Approximation to a Binomial Distribution.
