Answer:
1. The mean hemoglobin level in men is not equal to the mean hemoglobin level in women and
2. There is more hemoglobin in the average man than in the woman
Step-by-step explanation:
The confidence interval is from
-1.76 g/dl < μ₁ - μ₂ < -1.62 g/dl
Here we note that the range in the confidence interval for the difference between the two means lie in the negative part of the number line which is indicative of that μ₁ - μ₂ ≠ 0 or μ₁ ≠ μ₂
That is the statistic of the confidence interval implies that the mean hemoglobin level in men is not equal to the mean hemoglobin level in women and
That there is more hemoglobin in the average man than in the woman.
