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.
Assuming that you want to generalize to all cancer patients, all cancer patients would be the population, the 675 patients would be the sample, and the 76% and 63% are statistics.
In this scenario, the population would be all cancer patients who could potentially receive either the new drug Lafent or the standard chemotherapy drug. The sample would be the 675 cancer patients who actually participated in the medical study.
The population parameter given is the percentage of all cancer patients who received Lafent and were still living after eight months, which is 76%.
The sample statistic given is the percentage of the 675 cancer patients who received Lafent and were still living after eight months, which is also 76%.
