*Test Reliability* If a test that has a reliability *r* is lengthened by a factor *n*
*R* of the new test is given by

If the reliability is *r* = 0.6, the equation becomes

Find *R*(1).

Find *R*(2); that is, find *R* when the test length is doubled.

What percent improvement is there in the reliability when the test length is doubled?
