Roger is measuring the length of a hanging spring as various weights are added to it. using these measurements, he obtained the following regression equation: y = 0.006x + 11.5, where y is the length of the spring in centimeters and x is the mass added to the spring in grams.
what is the meaning of the coefficient 0.006 in this equation?
a.)the stretch of the spring by a weight of 1 gram is 0.006 times of that caused by a weight of 11.5 grams
b.) the length of the spring increases by 0.006 cm for every gram added to it
c.) a weight of 6 grams stretches the spring by 1 cm
d.) a weight of 11.5 grams stretches the sprin by 0.006 cm
