A random sample of 2000 adult women indicated that 1041 of them asked for medical assistance last time they felt sick. The same sized sample of men indicated that 993 of them asked for medical assistance. Use the z-values rounded to three decimal places to obtain the answers. a) Is it reasonable to conclude that women ask for medical assistance more often than men? Use a = 0.05. Find the P-value for this test. Round your answer to three decimal places (e.g. 98.765). P-value= i 0.016 b) Suppose that p₁ = 0.55 and p₂ = 0.5. Determine the sample size needed to detect this difference with a probability of at least 0.95.
