Weights of newborn babies in a certain state have normal distribution with mean 7.50 lb and standard deviation 1.25 lb. If the percentage of babies that weigh less than 5.63 lbs is 6.7%, then the percentage of babies that weigh more than _______ should also be roughly 6.7%.
Homework Answers
z value at 6.7% = 1.50
z = (x - mean)/s
1.50 = (x - 7.50)/1.25
x = 1.25 * 1.50 + 7.50
x = 9.38
