(d) A research was conducted at University Y to test the IQ score of the student based on their brain dominance. The researcher selected a random sample of 10 students with left-brain and a sample of 10 students with right-brain to test the IQ score. Without assuming the population is normally distributed, at a 5% significance level is there evidence that the left-brain dominance student scores more than right-brain dominance in the IQ test. The number of scores in the IQ test has been recorded as below: Left-brain Dominance Right-brain Dominance 100 89 150 79 120 90 140 110 134 120 110 120 160 169 169 100 98 99 122 130 (13 marks)
