Suppose that a 2009 survey revealed that 8.4% of people identified as either vegetarian or vegan. The owners of a chain restaurant are considering adding more vegetarian options to their menu but first want to know if the proportion of people who identify as either vegetarian or vegan, p, has increased since 2009. They choose a random sample of 500 people and find that 46, or 9.2%, are vegetarians or vegans. The restaurant owners plan to use this information in a one-sample z-test for a proportion. Select the appropriate null (Ho) and alternative (H1 ) hypotheses
