Entry to a certain University is determined by a national test. The scores on this test are normally distributed with a mean of 500 and a standard deviation of 100. Tom wants to be admitted to this university and he knows that he must score better than at least 70% of the students who took the test. Tom takes the test and scores 585. Will he be admitted to this university?
Homework Answers
Solution:- Given that mean = 500, standard deviation = 100
=> For x = 585,
z = (585-500)/100 = 0.85
=> P(Z < 0.85) = 0.8023 = 80.23%
Tom scored better than 80.23% of the students took the test and the will be admitted to this university.
