A study found that 11 out of 44 randomly selected adults said they agree that toddlers should not be taken out to eat at a restaurant. It was previously believed that 30% of adults agree that toddlers should not be taken out to eat at a restaurant. I there evidence to suggest an decrease in this rate? Which of the following is an appropriate set of hypotheses.
Ho: p = 0.30 Ha: p > 0.30
Ho: p = 0.30 Ha: p < 0.30
Ho: p =0.30 Ha: p = 0.30
