Suppose you manage Saras burger bar, you would like to analyze drink preferences for two different type of customers to determine if the drink preference is independent of customer ages which will help influence your beverage pricing and marketing of new beverages. a survey yeilds the following information. 

                                  Under 25 years                   25 years and over                     Total

Coffee                        112                                              206                                         318

Tea                             52                                                  99                                          151

Soft drink                   193                                            243                                           436

Other                         42                                               52                                            95

                                    400                                        600                                        1,000

What are the null and alternative Hypotheses?

Develop an expected frequency table? (assumption of independence)

calculate the test statistic, degrees of freedom and state the p-value from the appropriate table 

Can you reject the null hypothesis for a= .05?
