Sarah's parents are concerned about her height based on her pediatrician's records. The document asks to: 1) Estimate the correlation between age and height; 2) Compute the slope and intercept coefficients to determine the line of best fit equation; 3) Use the line equation to predict height at 40 and 72 months; 4) Compare Sarah's average monthly height growth based on the line to the average of 0.5cm growth per month for kids aged 4-5 to see if she is growing slower or faster.
