Prof. Gersch wishes to find a relationship between how many
hours students study and how they do on a departmental test. He
takes a random sample of 50 students, asks how many hours they
studied for their test and how they did on the test, enters the
data into a computer for analysis and finds the relation is given
by the following regression equation:
GRADE = 45.2 + 10.1*HOURS
Prof. Gersch, in this analysis, sees that the SSE is 24.
What is the standard error of estimation,Se ?
(Give your answer to three decimal places; eg, 0.400)
