1. In this scenario, identify the population, the sample, and any population parameters or sample statistics that are given.

A medical study followed 675 cancer patients who received either the new drug Lafent or a standard chemotherapy drug. 76% of those who receives Lafent were still living after eight months, compared to only 63% of those who received the standard chemotherapy drug.

In this scenario, the population would be all cancer patients. The sample would be the 675 cancer patients who participated in the medical study. The population parameter given is the proportion of all cancer patients who received Lafent and were still living after eight months (76%), and the population parameter for standard chemotherapy would be the proportion of all cancer patients who received standard chemotherapy and were still living after eight months (63%). These percentages represent the population parameters because they give information about the entire population of cancer patients.
