Question A physical therapist is interested in studying patients recovering from neck injuries. Let the proportion of neck injury patients who fully recover in less than 6 months be p. If the physical therapist wants to know if the proportion of neck injury patients who fully recover in less than 6 months is more than 75%, what are the null and alternative hypotheses? Select the correct answer below: H0: p=0.75; Ha: p>0.75 H0: p=0.75; Ha: p<0.75 H0: p>0.75; Ha: p=0.75 H0: μ=0.75; Ha: μ>0.75
