A least squares regression line was calculated to relate the length (cm) of newborn boys to their weight in kg. The line is weight = - 5.83 + 0.163 length. Explain in words what this model means. Should new parents (who tend to worry) be concerned if their newborn's length and weight don't fit this equation?

A least squares regression line was calculated to relate the length (cm) of newborn boys to their weight in kg. The line is weight = - 5.83 + 0.163 length. Explain in
words what this model means. Should new parents (who tend to worry) be concerned if their newborn's length and weight don't fit this equation?
What does the given model mean?
O A. The weight of a newborn boy can be predicted as - 5.83 kg plus 0.163 kg per cm of length.
O B. The minimum length of a newborn baby boy can be no less than 35.7669 cm.
O C. The weight of a newborn boy will always equal - 5.83 kg plus 0.163 kg per cm of length.
O D. The length of a newborn boy can be predicted as - 5.83 cm plus 0.163 cm per kg of weight.
Should new parents (who tend to worry) be concerned if their newborn's length and weight don't fit this equation?
O A. No, because this is a model fit to divide the data. All newborn weights above the line are normal and all newborn weights below the line are a matter for
concern.
O B. Yes, because 97% of new born babies fit into this linear model perfectly.
OC. No, because this is a model fit to data. No particular baby should be expected to fit this model exactly.
O D. Yes, because any newborn whose length and weight do not fit the model are far outside the normal weight to length proportion.
