Aregression analysis between weight (y in pounds) and height (x in inches) resulted in the following least squares line: y^i = 120 + 5x. this implies that if the height is increased by 1 inch, the weight, on average, is expected to: a. increase by 1 pound. b. decrease by 1 pound. c. increase by 5 pounds. d. increase by 24 pounds.

Option (c) increase by 5 pounds

Step-by-step explanation:

Data provided in the question:

The regression analysis between weight (y in pounds) and height (x in inches)

⇒ y = 120 + 5x

now,

on differentiating the above equation, we get

dy = 0 + 5dx

here,

dy is the change in weight

dx is the change in height

thus,

for, increase in height of 1 inch i.e dx = 1

we get

dy = 5(1)

or

dy = 5 pounds

here, positive value means increase in weight

therefore,

the correct answer is option (c) increase by 5 pounds

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:
