Transcribed Image Text:Arm span and Height
Estimating body disproportion is useful to assess the likelihood of a primary growth disorder in children. A pediatrician selected
eight healthy children aged 10 to 17 and measured the arm span and height of each of them. She collected the following results
(inches):
Arm span (x)
49
75
64
71
44932
52
67
78
57
Height (y)
52
73
64
SSxx = 792.875
72
52
69
81

To save computational time, you may use the following sums, sums of squares, and sum of cross-products for subsequent
calculations:
Ex = 513 2y = 522
SSyy = 759.5
SSxy
=765.75
