Problem 20E
A random sample of n = 900 observations is selected from a population with μ = 100 and σ = 10.
a. What are the largest and smallest values of that you would expect to see?
b. How far, at the most, would you expect to deviate from μ?
c. Did you have to know μ to answer part b? Explain.
ANSWER:
Solution 20E
Step1 of 4:
From the given problem we have:
n = 900,
and
Here our goal is:
a). We need to find the largest and smallest values of that we would expect to see.
b). We need to check how far, at the most, would you expect to deviate from μ.
c). We need to check whether we have to know μ to answer part (b).
