consider the gre scores for a random sample of 6 students out of a class of 25: name julia andrew jason cathy jessica robert sco
re 650 550 380 720 710 550 what is the point estimate for the mean score for students in the class?
1 answer:
Name Score
Julia 650
Andrew 550
Jason 380
Cathy 720
Jessica 710
Robert 550
Point estimate for the mean score:
Sample mean = sum of all observations / number of observations
sample mean = (650+550+380+720+710+550) / 6
sample mean = 3560 / 6
sample mean = 593.33
The point estimate for the mean score is 593.33
