Determine whether the results below appear to have statistical significance, and also determine whether the results have practical significance. In a study of a weight loss program, 77 subjects lost an average of 4141 lbs. It is found that there is about a 4040% chance of getting such results with a diet that has no effect. Does the weight loss program have statistical significance?

Answer:

No, the weight loss program doesn't have statistical significance.

Step-by-step explanation:

We are given that in a study of a weight loss program, 7 subjects lost an average of 41 lbs.

It is found that there is about a 40% chance of getting such results with a diet that has no effect.

Firstly, statistical significance means that the event is sure to be happen and there is a proper statistical calculation behind it.

But here it is stated that there is a 40% chance of getting such results with a diet that has no effect which means that the event is unlikely to happen by chance and it is just a prediction so, the weight loss program is not statistically significant.

Now, practically significant means that there is a large difference in the subjects being tested.

Here, the weight loss program is considered to be practically significant because there is a large amount of weight loss of 43 lbs of the subjects which is a large amount.
