Write the null and alternative hypotheses you would use to test the following situation. The county health department has concerns about the chlorine level of 0.4% mg/mL at a local water park increasing to unsafe level. The water department tests the hypothesis that the local water park's chlorine proportions have remained the same. What are the null and alternative hypotheses?

a)H₀: p = 0.004 H_A: p > 0.004

b)H₀: p = 0.004 H_A: p < 0.004

c)H₀: p > 0.004 H_A: p < 0.004

d)H₀: p > 0.004 H_A: p = 0.004

e)H₀: p = 0.004 H_A: p 0.004
