Answer:

The weight loss program is statistically significant.

Step-by-step explanation:

We can define a statistically significant difference or result as a result which is not attributed to chance. In other words we can say that a statistical significance shows if the difference observed between groups is real or if it has occurred simply due to chance.

Here, given is that 40 subjects lost a mean of 3.0 lb after 12 months.

So, here the weight loss program is statistically significant as the results are unlikely to occur by chance.
