The major themes behind Chapter 10 are...

 

    1.    Dependent and Independent Samples

            a.    Understanding the difference between

                   independent and dependent samples.

                    i.    Dependent is a comparison between two

                          values.  Ordered Pairs.

                    ii.   Independent is when two samples could

                          stand alone.  Samples Size

                          doesn’t have to be the same.

   2.    Inference Concerning the Mean Difference.

          Dependent Samples

            a.    Must choose the correct Alternative

                   Hypothesis.

                    i.    Subtraction between the ordered pairs is

                          important.

            b.    Use of t-distribution

                    i.    Same as Last Chapter.

            c.    Hypothesis Testing Concerning Mean

                   Difference (Dependent) and

                   Confidence Interval

                    i.    State Null and Alternative Hypothesis/

                          State Estimation

                    ii.    Verify Conditions

                            1)    Check SRS

                            2)    Check Normality (Box and

                                   Whiskers, Probability Plot, etc.)

                            3)    Check Sample Size.  (Number of

                                   ordered pairs)

                    iii.    Calculations.

                    iv.    Explanation of calculation.

 

   3.    Inferences Concerning the Mean Difference.

          Independent Samples

            a.    Must choose the correct Alternative

                   Hypothesis

            b.    Hypothesis Testing Concerning Concerning

                   Mean Difference and

                   Confidence Interval

                    i.    State Null and Alternative Hypothesis/

                          State Estimation

                    ii.    Verify Conditions

                            1)    Check SRS

                            2)    Check Normality (Box and

                                    Whiskers, Probability Plot, etc.)

                            3)    Check Sample Size.  (Use smaller

                                    Sample Size for df)

                    iii.    Calculations

                    iv.    Explanation of calculation.

 

   4.    Inferences Concerning the Proportion Difference.

            a.    Must choose the correct Alternative

                   Hypothesis

            b.    Hypothesis Testing Concerning Concerning

                   Proportion Differnce and

                   Confidence Interval

                    i.    State Null and Alternative Hypothesis/

                          State Estimation

                    ii.    Verify Conditions

                            1)    Check SRS

                            2)    Check np and nq (All 4 must satisfy

                                    the condition)

                            3)    Check Sample Size.  Sample Size

                                    < 1/10 of Population

                    iii.    Calculations (Watch out on

                            Testing...different Standard Error)

                    iv.    Explanation of calculation.
