1. A company manager hired an economicresearcher to study watch preference of theprospective customers. The researchersampled 30 customers and each is classifiedby age and watch type preference (digital vsanalog). Using the following data, determineif there is an association between age andwatch preference using your SPSS software: 1. What would be your null hypothesis?2. What would be the alternativehypothesis?3. What is your computed X2 value?4. What is your decision (use a = 0.05)?5. What is you interpretation?
