It is believed that 11% of all Americans are left-handed. A college needs to know the number of left-handed desks to place in the large instructional lecture halls being constructed on its campus. In a random sample of 350 students from that college, whether or not a student was left-handed is recorded for each student. The college wants to know if the data provide enough evidence to show that students at this college have a higher percentage of left-handers than the general American population. State the random variable, population parameter, and hypotheses. State the Type I and Type II errors in the context of this problem. The symbol for the random variable involved in this problem is The wording for the random variable in context is as follows: The symbol for the parameter involved in this problem is The wording for the parameter in context is as follows: Fill in the correct null and alternative hypotheses.�0: ��: A Type I error in the context of this problem would be A Type II error in the context of this problem would be
