Hello! I have a stats exam on Saturday and I'm stuck on this question. I know the answer is c) I just don't understand how to find it....

Suppose that 30% of people taking a certain medication experience dizziness. A new formulation of the medication is created and tested in order to see if it decreases the incidence of dizziness. It is tested on 20 people, and only 3 of them experience dizziness. Do these result suggest that the new formulation is effective in decreasing the incidence of dizziness?

(a) Yes, because 3 out of 20 is only 15%.

(b) Yes, because 3 is less than 3.95.

(c) No, 3 is not significantly low because it is not less than 1.9

(d) No, 3 is not significantly low because it is not less than 2.93 (e) No, because .0742 is not less than .05.
