12. We Are Interested In Predicting A Woman's Body Mass Index From Her Waist Circumference. We Have Body Mass Index (BMI) And Waist Circumference Measurements For 14 Female Subjects, And These Are Given In The Table Below, Together With The Summary Statistics. Subject BMI (Kg/M) 19.6 23.8 19.6 201 25.2 21.4 22.0 27.5 33.5 20.6 29.9 Waist Circumference (Cm)

 

12. We are interested in predicting a woman's body mass index from her waist circumference. We have body mass index (BMI) and waist circumference measurements for 14 female subjects, and these are given in the table below, together with the summary statistics.

The slope is 0.386. The intercept is -6.573. Write the linear regression equation in the context of this application. (2) Use the linear least-squares regression equation to find the predicted BMI of a woman whose waist circumference is 70 cm.
