A research was conducted at University Y to test the IQ score of the studentbased on their brain dominance. The researcher selected a random sample of 10students 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
A research was conducted at University Y to test the IQ score of the studentbased on their brain dominance. The researcher selected a random sample of 10students with left-brain and a sample of 10 students with right-brain to test the IQ score. Without assuming the population is
Let X denotes the Left-brain Dominance
& Y denotes the Right-brain Dominance
To test whether the left-brain dominance student scores more than right-brain dominance in the IQ test. the hypothesis of interest is
H0: μx=μyH1: μx>μy
Computation of test statistic and p-value:
- Select STAT>TESTS>2-Samp T-Test.
- Enter the appropriate values under "EDIT" option.
- Select Calculate and press Enter.
- Select µ1: >µ2 as alternative.
- Under “Pooled”, select “Yes”.
