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 290 students from that college, whether or not a student was left-handed was 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? Describe the sample statistic, population parameter, and hypotheses. State the Type I and Type II errors in the context of this problem. The sample statistic in context is as follows: Select an answer The mean number of all students from that college that are left-handed. The percentage of 290 randomly selected students from that college that are left-handed. 11% of all students from that college are left-handed. Whether or not a randomly selected student from that college is left-handed. The percentage of all students from that college that are left-handed. The mean number of 290 randomly selected students from that college that are left-handed. A randomly selected student from that college. A randomly selected student from that college that is left-handed The population parameter in context is as follows: Select an answer The mean number of 290 randomly selected students from that college that are left-handed. A randomly selected student from that college that is left-handed The percentage of all students from that college that are left-handed. A randomly selected student from that college. The mean number of all students from that college that are left-handed. Whether or not a randomly selected student from that college is left-handed. 11% of all students from that college are left-handed. The percentage of 290 randomly selected students from that college that are left-handed. c) Fill in the correct null and alternative hypotheses: H0:H0: pp? > ≥ = < ≤ ≠ HA:HA: pp ? ≤ ≠ ≥ < = > e) A Type II error in the context of this problem would be:
