According to most estimates, 10% of the people in the general population are left-handed and 90% are right-handed. A neurological theory of handedness and cerebral dominance predicts that there should be a disproportionate number of left-handers among artists. For a sample of n=150 artists, a psychologist finds that 24 are left-handed. Is there a higher proportion of left-handers among artist than there is for the general population? Test with alpha set at 0.05. Please go through from step 1 (research question) to step 6 (make decision) and write down your answers for each step.
