researcher is creating a new treatment protocol for Myelodysplastic Syndrome (MDS), a form of preleukemia. Following the old treatment protocol, 28% of patients with MDS will develop leukemia within 5 years of MDS diagnosis. He believes his new treatment protocol will lead to fewer MDS patients developing leukemia. He takes a random sample of 100 individuals on his new treatment protocol. Of these 100 individuals, 20 develop leukemia within 5 years of MDS diagnosis. Conduct a hypothesis test at the 10% level to test this claim that his new treatment protocol will lead to fewer MDS patients developing leukemia. What are the hypotheses? a. H0: p = 0.28; HA: p < 0.28 b. H0: p > 0.28; HA: p < 0.28 c. H0: p = 0.28; HA: p = 0.20 d. H0: p̂ = 0.28; HA: p̂ < 0.28 e. H0: μ = 28; HA: μ ≠ 28
