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 340 students of its 34120 students, 48 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? Use a 10% level of significance. P: PARAMETER What is the correct parameter symbol for this problem? P vv What is the wording of the parameter in the context of this problem?
