The American Academy of Health and Fitness released a survey, revealing that 35% of US adolescents admit they lie to their doctor about how often they eat vegetables. Dr. Vincent believes that the percentage is different than what is shown by the survey results. She decides to conduct her own hypothesis test to determine the true proportion. What should she write as the null and alternative hypotheses for this situation?
H0: μ = 0.35; Ha: μ > 0.35
H0: μ = 0.35; Ha: μ < 0.35
H0: p = 0.35; Ha: p > 0.35
H0: p = 0.35; Ha: p < 0.35
H0: p = 0.35; Ha: p ≠ 0.35
