Final answer:
The null and alternative hypotheses to test for equality in mean diastolic blood pressure between women and men, using a 0.05 significance level, are H0: μw = μm and Ha: μw ≠ μm.
Step-by-step explanation:
The question is asking you to formulate the null and alternative hypotheses to test the claim that women and men have the same mean diastolic blood pressure using a 0.05 significance level. The correct null and alternative hypotheses for a two-tailed test about equality (or non-equality) of two means are H0: μw = μm and Ha: μw ≠ μm. This means we are testing if there is a difference in either direction (higher or lower) between females (μw) and males (μm) mean diastolic blood pressure, without specifying which one we expect to be higher. Answer A represents this case and is the correct choice.
