The following are Wechsler's IQ scores of students who took the IQ test under a very noisy environment: 105, 104, 90, 86, 102, 100, 85, 93, 98, 97, 103, 99, 100, 95, 89, 90. Do these scores suggest that noise really made a difference in their IQ (at the .05 level)? Find out using the step-by-step procedure for Null Hypothesis Testing.
