We wish to estimate the mean serum indirect bilirubin level of 4-day-old infants. The mean for a sample of 16 infants was found to be 5.98 mg/100 cc. Assume that bilirubin levels in 4-day-old infants are approximately normally distributed with a standard deviation of 3.5 mg/100 cc.

What is the distance between the points 4,10 and -3,-14 on the coordinate plane

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1
