In each of the following situations, identify the population, the units, and each variable that is measured, and tell if each variable is categorical or numerical. A.) A quality control worker with Sweet-Tooth Candy weighs every 100th candy bar to make sure it is very close to the published weight. Population: ? Units: ? Variable Measured: ? Categorical or Numerical: ? B.) Doris decides to clean her sock drawer out and sorts her socks into piles by color. Population: ? Units: ? Variable Measured: ? Categorical or Numerical: ? C.) A researcher is studying the effect of a new drug treatment for diabetes patients. She performs an experiment on 200 randomly chosen individuals with type II diabetes. Because she believes that men and women may respond differently, she records each person’s gender, as well as the person’s change in blood sugar level after taking the drug for a month. Population: ? Units: ? Variable Measured: ? Categorical or Numerical: ?
