You task is to help Samuel solve the following questions using the following formula related to standard error of measurement (SEM), standard deviation (SD), and reliability of the test. (Show all you computational work)

SEM = SD * squared root of (1-reliability)

1. Form A of the final exam has a standard deviation of 20 and a reliability of .75. What is the standard error of measurement for Form A?

20*.5=10

2. A student, Susan, had a score of 83 on Form A. What does her true score fall at a 95% confidence level?

3. Form B has a standard error of measurement of 6 with a reliability of

Question

You task is to help Samuel solve the following questions using the following formula related to standard error of measurement (SEM), standard deviation (SD), and reliability of the test. (Show all you computational work)

SEM = SD * squared root of (1-reliability)

1.	Form A of the final exam has a standard deviation of 20 and a reliability of .75. What is the standard error of measurement for Form A?

20*.5=10

2.	A student, Susan, had a score of 83 on Form A. What does her true score fall at a 95% confidence level?

3.	Form B has a standard error of measurement of 6 with a reliability of
