a random sample of n 900 observations is selected from a po

a random sample of n = 900 observations is selected from a population with u = 100 and sigma = 10

a) what are the largest and smallest values of x that you would expect to see?

b) how far, at the most, would you expect x to deviate from u?

c) did you have to know u to answer part b? Explain.

Solution

a.The largest and the smallest value of x is:

x+/-mu*sigma

=x+/-100*10=x+/-1000
