A manager at a casual dining restaurant noted that 18% of customers ordered soda with their meal. In an effort to increase soda sales, the restaurant begins offering free refills with every soda order for a two-week trial period. During this trial period, 21% of customers ordered soda with their meal. To test if the promotion was successful in increasing soda orders, he manager wrote the following hypotheses: H0: p=0.18 and Ha: p=0.21, where p represents the proportion of customers who ordered soda with their meal during promotion. Are these hypotheses written correctly? Correct any mistakes as needed.
