Public Health and Nutrition Research suggests that salt intake is related to fluid intake in adults and soft drink consumption in children and adolescents. Suppose a random sample of 18 children and adolescents was obtained and the amount of salt consumed (x, g/week) and the amount of sugar-sweetened soft drinks consumed (y, g/week) was recorded for each. The following summary statistics were obtained.

ΣX_i = 430
ΣY_i = 17,512
ΣX_iy_i = 441,608
ΣX_i² = 11,138
ΣY_i² = 18,197,768
