Question 1109233: The average GPA at four year colleges and universities is 3.11 (sd=.30)
a. after more research, i found that the average GPA for graduate school is 3.5. If you are interested in a masters program, you have to earn GPA in the top ____% undergraduates
b. A student claims that he has a higher GPA than 95% of students at university123 for this claim to be true, what would his GPA have to be?
You can put this solution on YOUR website! Assuming we know the population sd, use z - test, where z=(x-mean)/sd
z> (3.5-3.11)/0.3 or > 0.39/0.3 or > +1.3
That probability is 0.0968 so the top 9.68% or 9.7%
The 95% percentile is z=1.645
1.645=(x-3.11)/.3
0.4935=x-3.11
x=3.60 GPA.
