Answer:

In terms of size it is adequate . Sample isn't randomly selected

Step-by-step explanation:

In order for the sampling ot be adequate the sample size must be large enough which in this case it is. The samples must also be randomly selected. Here, the sample includes students from one course only. In order for the study to represent whole population that is college students, students from other courses must also be included. Junior as well as senior students must also be part of this study.

I'm pretty sure it was Step One. When you multiply -1/4, I don't think the symbol is supposed to change to an addition sign. It's supposed to still be a minus sign.
