Suppose that the age of students at George Washington Elementary school is uniformly distributed between 5 and 11 years old. 41 randomly selected children from the school are asked their age. Round all answers to 4 decimal places where possible. What is the probability that the average of 41 children will be between 8 and 8.4 years old?                              How would I do this with a TI84 calculator?
