Answer :

The given statement "A two-factor study compares 2 levels of factor A and 3 levels of factor B with a sample of n = 5 participants in each treatment condition. This study uses a total of 25 participants." is true.

The term probability refers the occurrence of a random event.

Here we have given the statement "A two-factor study compares 2 levels of factor A and 3 levels of factor B with a sample of n = 5 participants in each treatment condition. This study uses a total of 25 participants."

And we have to identify whether this one is true or not.

While looking into the given question, we have identified the value like the following,

level in factor A = 2

levels in factor B = 3

Number of participants = 5

Then the total number of participants is calculated as,

=> (3 + 2)  x 5

Now, we have to expand the given equation, then we get,

=> 5 x 5

Then the total number of participants is 25.
