Transcribed Image Text:Overall, what proportion of the students did not pass the test? Leave your answer as an unreduced fraction. Answer: Blank 1: Blank 2:
A teacher designed an experiment to see whether students would do better on a quiz when it was copied onto yellow paper rather than the usual white paper. She gave the same test to her first and fifth period classes, randomly selecting the class that would get the test copied onto yellow paper. The other class got the test copied onto white paper. After grading the test, she found that 25 of the 40 students who took the test on yellow paper passed the test as did 30 of the 38 students who took the test on white paper.
