I need help with this question!
The following data represent the
relative frequencies of live multiple-delivery births (three or more
babies) in 2002 for women 15 to 44 years old.
Age Relative Frequency15-19. 0.012820-24. 0.070225-29. 0.223530-34. 0.388835-39. 0.253040-44. 0.0518
Suppose the data is normally distributed with mean 31.77 and standard deviation 5.19 years.
Compute the proportion of multiole birth mothers in each class by finding the area under the normal curve.
