A psychologist has designed a new intelligence test. She has constructed two forms of the test, Forms A and B, and she claims that both forms measure intelligence equally well. She randomly selects 11 subjects and has each of them write Form A and Form B) She computes the correlation between the forms to be + .80. At a = .05, use a non-directional alternative to test her claim that the two forms measure the same thing. Note: tcrit = ± 2.262. What is the standard error?
What will be an ideal response?
