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 100 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 different percentage of left-handers than the general American population? State the random variable, population parameter, and hypotheses. State the Type I and Type Il errors in the context of this problem. a) The symbol for the sample variable involved in this problem is ? ✓ The sampling distribution of this variable in context is as follows: Select an answer b) The symbol for the parameter involved in this problem is ? ✓ The wording for the parameter in context is as follows: Select an answer c) Fill in the correct null and alternative hypotheses: Ho: ? ? ✓ Ha: ? ✓ ? ✓
