Question

Large samples o women and men are obtained, and the hemoglobin level is measured in eac ect Here is e 95% con dence interval for the difference between the O population means where he measures from wo men correspond o population 1 and su the measures from men correspond to population 2:ー1.75 g /dLe μ 1-12 -1 62 g/dL. Complete parts (a) through (C) below. a. What does the confidence interval suggest about equality of the mean hemogiobin level in women and the mean hemoglobin level in men? Because the confidence interval (Type an integer or a decimal. Do not round) b. Wrie a brief statement that interprels that confidence interval. ▼ し appears that there 'l a significant difference between the mean level ot hemoglobin in women and the mean level 0, hemoglobin in men O A. There is 95% confidence that the interval from-1.75 g /dL to-1.62 g/dL actualy contains the value of the difference between the two population means ( ○ B. There is 95% confidence that the interval from-1 76 g/dL to-1.62 g/dL does not contain the value or the difference between the two population means ( O c. There is 95% conndence that the dmerence between the two population means (μ1-μ2) is either-1.76 g/dL or-1 62 g/dL. 0 D. There is 95% confidence that the difference between the two population means is not 0 c. Express the contidence interval with measures from men being population 1 and measures from women being population 2. Choase the correct answer below -u2} -μ2} OA. ○ B. O c. OD, -1.76 g/dL«m-u2 <-1.62 g/dL 1.62 g/dL < μ1-μ2 < 1.76 g/dL -1.76 g/dL c μ1-u2< 1.62 g/dL -1.62 g/dLe -μ2 < 1.76 g/dL
