Question 417766: The average salary is $37,529. normal distribution with o- =$6200. sample of 75 teachers, what is the probability that the sample mean is greater than $37,987. The correction factor is ignored Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! The average salary is $37,529. normal distribution with o- =$6200. sample of 75 teachers, what is the probability that the sample mean is greater than $37,987. The correction factor is ignored
------------------
t(37987) = (37987-37529)/[6200/sqrt(75)] = 0.639741
==============
P(x-bar > 37987) = P(t> 0.6397 when df = 74) = 0.2622
===============
