Answer:
0.980
Step-by-step explanation:
Use a calculator with built-in distribution functions.
Example:
normcdf(-2.05, 10000) = 0.980
So if there are twenty children and 6 have an average age of five, you could say their total age together is 30 years. The others (20-6) have an age of 8.
30+ (20-6)*8 = total age of every child at the library. From there divide by the number of children.
