It is believed that 11% of all Americans are left-handed. A college needs to know how many left-handed desks to place in the big lecture halls being constructed on its campus. In a random sample of 200 students from that college, 30 were left-handed. Does this provide enough evidence to show that students at this college have a higher percentage of left-handers than the general American population? Set up the hypotheses. a.)
