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 150 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 lower 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 sample variable involved in this problem is p The sampling distribution of this variable in context is as follows: b) The symbol for the parameter involved in this problem is p The wording for the parameter in context is as follows: c) Fill in the correct null and alternative hypotheses: The percentage of 150 randomly selected students from that college that are left-handed.
