Question:
Do left-handed or right-handed people make more money? One study recorded the hourly earnings for a random sample of 2295 American men, of whom 2027 were right-handed and 268 were left-handed. The righthanded men earned an average of $13.10 per hour, while the left-handed men earned an average of $13.40 per hour. The sample standard deviation for both left-handed and right-handed workers was about $7.90. Test the hypothesis that the average earnings for left-handed and right-handed men are the same. Be sure to state the null and alternative hypotheses, find the test statistic and p-value, and interpret the conclusion.
