Q1. Height Analysis: The following measurements show the respective heights in inches of ten fathers and their eldest sons. Father 67 63 66 71 69 65 62 70 61 72 Son 68 66 65 70 69 67 64 71 60 63 Estimate the height of son for the given height of father as 70 inches. Compute coefficient of correlation and explain what does it means
Added by M-Nica M.
Step 1
504 \) - \( \beta = 0.50744 \) - \( x = 70 \) Substitute the values into the equation: \[ y = 32.504 + 0.50744 \times 70 \] \[ y = 32.504 + 35.3218 \] \[ \mathbf{y = 67.8258} \] Show more…
