Chapter 9

 

The major themes behind Chapter 8 are...

 

    1.    Inference Concerning the Mean (SD - Unknown)

            a.    First thing, to understand the t-Distribution.

            b.    Confidence Interval using the t-Distribution

                   for a Population Mean

                    i.    State what you are trying to estimate.

                    ii.    Verify Conditions

                            1)    Check SRS

                            2)    Check Size of sample

                            3)    Check Distribution

                    iii.    Calculations

                    iv.    Explanation of calculation.

            c.    Hypothesis Testing using t-Distribution (One

                   Sample)

                    i.    State Null and Alternative Hypothesis

                    ii.    Verify Conditions

                            1)    Check SRS

                            2)    Check Size of sample

                            3)    Check Distribution

                    iii.    Calculations

                    iv.    Explanation of calculation.

 

    2.    Inference Concerning Binomial Probability

            a.    Reminder of Binomial Probability

            b.    Confidence Interval for Binomial Probability

                    i.    State what you are trying to estimate.

                    ii.    Verify Conditions

                            1)    Check SRS

                            2)    Check Distribution (np-hat and nq-

                                    hat)

                            3)    Check Sample Size

                    iii.    Calculations

                    iv.    Explanation of calculation.

            c.    Hypothesis Testing Concerning Binomial

                   Probability (One Sample)

                    i.    State Null and Alternative Hypothesis

                    ii.    Verify Conditions

                            1)    Check SRS

                            2)    Check Distribution (np and nq)
