Researchers constructed the following simple linear regression model to predict hip girth (in cm) using weight (in kg): Predicted hip girth = 70.27 + 0.38 (Weight) Interpret the slope: For every 1 kg increase in weight, the predicted hip girth increases by 0.38 cm. Flag question: Question 13 Question 131.5 pts In a longitudinal study 93 children were followed for nearly 18 years. Their heights (in cm) were measured at different time points. Researchers want to know if height at age 1 can be used to predict height at age 18. They used statistical software to run a simple linear regression model. All assumptions were met and there output follows: Simple Regression: Height at Year 18 versus Height at Year 1 Analysis of Variance Source DF Adj SS Adj MS F Value P Value Regression 1 2495.92 2495.92 40.38 < 0.0001 Error 91 5625.17 61.82 Total 92 8121.09 Model Summary S R-sq R-sq(adj) 7.86225 30.73% 29.97% Coefficients Term Coef SE Coef T Value P Value Constant 52.03 18.92 2.75 0.0072 Height at Year 1 1.6063 0.2528 6.35 < 0.0001 Regression Equation Height at Year 18 = 52.03 + 1.6063 Height at Year 1 Scatterplot with line of best fit for
