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 360 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 different 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. a. The symbol for the random variable involved in this problem is p b. The wording for the random variable in context is as follows: The percentage of 360 randomly selected students from that college that are left-handed. c. The symbol for the parameter involved in this problem is p d. The wording for the parameter in context is as follows: The percentage of all students from that college that are left-handed. e. Fill in the correct null and alternative hypotheses. Ho: HA: P V OB = V 8
