Answer:

Hello some parts of your question is missing below is the missing part

suppose we use a person's dad's height to predict how short or tall the person will be by building a regression model to investigate if a relationship exists between the two variables. Suppose the regression results are as follows:

Least Squares Linear Regression of Height

Predictor

Variables    Coefficient    Std Error T P

Constant    20.2833    8.70520 2.33    0.0223

DadsHt 0.67499 0.12495    5.40    0.0002

R² 0.2673 Mean Square Error (MSE) 23.9235

Adjusted R² 0.2581    Standard Deviation 4.9000

Answer : We expect most of the sampled heights to fall within 9.8 inches of their least squares predicted values.

Step-by-step explanation:

standard deviation is the statistical measurement of the level at which a dataset disperses from its mean value

interpreting the standard deviation in this problem ,

given that the standard deviation is 4.9 inches, it simply means that the dataset heights will be either +4.9 inches or -4.9 inches away from the mean value. this means that most of the sampled Dad/'s height will fall within 9.8 inches of their least squares predicted values
