This week, we consider how to conduct hypotheses test on one sample data. Discuss the concepts associated with these tests. Consider the following: 

·       What is the importance of the null hypothesis? Why has it been the backbone of mainstream hypothesis testing for decades?

• The difference between a one tail and a two tailed test. 
• The importance of stating the null and alternative hypotheses before conducting the test. 
• What is the difference between a type I and type II error? The importance of a type one error (p) in conducting the test.  What are its limitations?   What are the implications in the context of accepting or rejecting a null hypothesis?
• The relationship between the p value and our decision to accept or reject the null hypothesis
