Which of the following is the best hypothesis for this

A group of medical researchers investigated the effects of Drug X on lowering cholesterol levels in a group of men between the ages of 50 and 70 years old. The researchers did the following experiment and obtained the indicated results: One group of 150 men took a tablet containing Drug X for 3 weeks – 95 of these men decreased their cholesterol levels by at least 10% (three men from this group dropped out of the study). Another group of 150 men was given a tablet with no added Drug X for 3 weeks – 10 of these men decreased their cholesterol levels by at least 10% (two men from this group dropped out of the study).Which of the following is the best hypothesis for this experiment?
a) Will drug X lower cholesterol levels in men between the age of 50 and 70 years?b) Drug X will lower cholesterol levels in men.c) Since high cholesterol levels significantly increases several health risks for men, drug X is most likely beneficial.d) Men between the age of 50 and 70 years will have reduced cholesterol levels if they take drug X over a 3 week period.e) There is no significant difference in cholesterol levels between men that take drug X and those that don’t take it.
Which of the following was the control group in this experiment?
a) The amount of Drug X contained in the tabletb) The number of participants in each group at the end of the experimentc) The group of participants that received tablets containing Drug Xd) The group of participants that received tablets that did not contain Drug Xe) The number of participants in each group at the beginning of the experiment
Which of the following is a dependent variable in this experiment?
a) The amount of Drug X contained in the tabletb) Participants that received tablets containing Drug Xc) The average age of the participantsd) Number of participants in each group at the beginning of the experimente) Blood pressure
