a) What is the difference between a normal distribution and a standard normal distribution?
b) What is the purpose of using a standard normal distribution instead of the normal distribution?
c) Please cite one example of how the standard normal distribution is used, including the Z-values for your example.
d) If you are given the level of significance, how do you obtain the critical value?
e) How are z-values related to hypothesis testing?
f) Describe the five-step hypothesis testing process?
Give an example of a problem (business, political, scientific) in which ANOVA analysis would be appropriate. (Hint: the dependent variable is categorical, such as male vs. female or comparing three different types of fertilizer.)
The mean height of a certain plant is 160 centimeters. Suppose a botanist wants to carry out a hypothesis test to see if the mean height when these plants are treated with a certain chemical differs from 160. What is the null hypothesis and the al..
