We want to determine whether there is a linear relationship between people’s height as an adult and their height at $10$ years old. Here is some computer output showing results of a least-squares regression analysis for $y$ = adult height and $x$ = height at $10$ years old for a random sample of $11$ males. Term | Coef | SE Coef | T-Value | P-Value - | - | - | - | - Constant | $39.8$ | $16.1$ | $2.48$ | $0.035$ $10$ year height | $0.519$ | $0.289$ | ??? | ??? **Which of the following is the equation of the least-squares regression line for predicting adult height from height at $10$ years old?** [[☃ radio 1]]
