The weight, y, in pounds, of human babies was tracked for the first 12 weeks after birth where t represents the number of weeks after birth. The linear model representing this relationship is ŷ = 6.7 + 0.52t. Clarissa wanted to predict the weight of a baby at 16 weeks.

The weight of a baby at 16 weeks will be 15.02 pounds.

Explanation:

Hi, to answer this question we simply have to replace y=16 (number of weeks) in the equation given:

y = 6.7 + 0.52t

Replacing with the value given:

y= 6.7 + 0.52(16)

Solving for y (weight)

y = 6.7+8.32

y = 15.02

The weight of a baby at 16 weeks will be 15.02 pounds.
