CCC is buying some individual desks for its students and wants to know what percentage of left-handed desks to buy. The buyer's current best guess at the fraction of people who are left-handed is 10% (from historical data), but they know that our statistics students are very good and seeks their advice. The buyer wants to know if the percentage of CCC students who are left-handed is different from 10%. The statistics student decides to poll 380 students about their handedness. What is the random variable? What is the parameter? The random variable is the number of people in the sample who are left-handed and the parameter is the percentage of all CCC people who are left-handed. The random variable is the percentage of all CCC people who are left-handed and the parameter is the number of people in the sample who are left-handed. The random variable is the number of people in the sample who are left-handed and the parameter is the mean of all CCC people who are left-handed. The random variable is the mean of all CCC people who are left-handed and the parameter is the number of people in the sample who are left-handed.
