(a) Women in the sample, on average were as healthy as people nationally from both a physical and mental health perspective as indicated by the SD deviation of 10.0 and a mean of 50.0 based on the national average.
(b) The correlation is both above and below the diagonal.
(c) The strongest correlation in the matrix is the physical and mental health sample population with a physical health score with an r = -134 and mental health component score of r -133.
(d) What is the strongest correlation in this matrix is doctors' visit and physical health component.
(e)The weakest correlation in the matrix is body mass index (bmi) and mental health component
(f) In this analysis the variable with the strongest correlation with women's body mass index (bmi) is the number of doctors' visits.
