Suppose that the age of students at George Washington Elementary school is uniformly distributed between 5 and 11 years old. 45 randomly selected children from the school are asked their age. Round all answers to 4 decimal places where possible.

  1. What is the distribution of XX? XX ~ U(,)
  2. Suppose that 45 children from the school are surveyed. Then the sampling distribution is
  3. What is the distribution of ¯xx¯? ¯xx¯ ~ N(,)
  4. What is the probability that the average of 45 children will be between 8 and 8.6 years old?

Over the entire six years that students attend an Ohio elementary school, they are absent, on average, 28 days due to influenza. Assume that the standard deviation over this time period is σ = 9 days. Upon graduation from elementary school, a random sample of 36 students is taken and asked how many days of school they missed due to influenza. What is the expected value for the sampling distribution of the number of school days missed due to influenza?...
