Hi guys, I've had trouble with this one problem:
A doctor claims that three tablespoons of pure virgin coconut oil daily can reduce weight. To test the doctor’s claim, a researcher studied two groups of 25 women aged 35 to 40 years with weights between 130 to 140 pounds. He administered the three tablespoons of pure virgin coconut oil daily for a period of three months to one group of women only. After three months, he weighed the two groups of women.
1. identify the two populations of interest
2. identify the samples
3. identify the variables of interest
my teacher gave us a hint that the population is not "all women" or something along those lines.
