Question

A company is testing a new weight-loss supplement. For the study, the company enrolled 189 obese or overweight middle-aged people who agreed to take a weight-loss supplement for eight weeks. Half took the supplements and half took a placebo. A representative portion of their results is shown in the table below. What conclusions can you draw from this portion of the results?

Answer 1

Where is the table hun?

Answer 2

Could you attach a picture of the table? The one you pasted is kind of confusing

Answer 3

I think for the first one it is A because the supplement worked 7/8 of the time while the placebo worked 1/4 of the time

Answer 4

or 2/8, which is much less than the actual supplement

Answer 5

Hmm give me a second

Answer 6

D. They both use DNA as their genetic material

Answer 7

Suppose that \[f(x)\] equates to the change in weight.

When the data points are plotted, the placebo group has an ascending linear equation of \[f(x)=0.0488x - 7.2038\]
If you graph the placebo data, notice that m>0 and that the majority of the clustered data is above the x-axis (y=0 means no weight change) suggesting that placebo members gained variable weight cumulatively.

On the other hand, the supplement group has a descending linear equation of \[f(x) = -0.0566x + 6.8969\]

If graphed, notice that m<0 and that the majority of the clustered data is below the x-axis suggesting that the supplemented group lost variable weight cumulatively.

Also note, that both equation have a low R-squared value suggesting that more data is needed for this correlation to be statistically significant.

Answer 8

@Cardinal_Carlo I don't think you needed to make the answer so complicated haha.. and np @sofia.gulick

Answer 9

@doafan I hadn't thought my response was that complicated. I would say it was instead a clear and thorough interpretation of @sofia.gulick's data but thank you for the humor

Answer 10

@Cardinal_Carlo Ahh it's fine, as long as Sophia understood the question/answer :P
