You work at Happy Joe's family restaurant and want to see if customer meal satisfaction and gender are related to one another. You take a sample of customers and ask them if they were satisfied with their meal and note their gender. What is the appropriate conclusion at the 0.05 level of significance? There are two correct answers.   2)  We conclude that Satisfaction and Gender are related to each other, based on a p-value of 0.0025   3)  We determine that Satisfaction and Gender are independent of one another, based on a p-value of 0.0025   4)  We conclude that Satisfaction and Gender are not related to each other, based on a p-value of 0.9975   5)  We decide that Satisfaction and Gender are associated with each other, based on a p-value of 0.9975
