12. The Law School Admission Test (LSAT) is designed so that test scores are normally distributed. The mean LSAT score for the population of all test-takers in 2005 was 154.35, with a standard deviation of 5.62. Calculate the value of the standard error of the mean for the sampling distribution for 100 samples. (0.5 Points)
Solution,
Given,
Mean (
)
= 154.35
standard deviation (
)
= 5.62
n = 100
Standard error of the mean (
)
= 
 / 
n
                                              
= 5.62 / 
100
= 0.562
