At a certain university, the average attendance at basketball games has been 2700 spectators per game. The attendance for the first 11 games has been 2250 spectators per game with a sample standard deviation of 650. The athletic director claims that the attendance is the same as last year. If α = .05, what are the critical values?
-----
Ho: u = 2250
Ha: u # 2250
----
Ha implies a 2-tail test with alpha = 5% divide equally in 2 tails.
---
Therefore:: critical values are z = -1.96 and z = +1.96
