Stats Is this drug effective for heartburn!

A new antacids drug was given to a group of 25 patients who had heartburn. Five hours after taking the new drug, 20 of the them reported that their heartburn had disappeared. From this information you conclude:

(a) that the drug is effective for the treatment of heartburn.
(b) nothing, because the sample size is too small.
(c) nothing, because there is no control group for comparison.
(d) that the new treatment is better than omeprazole.
(e) that the drug is not effective for the treatment of heartburn.

(c) No control group, thus we don't know if other patients who had not been treated with the drug or given placebo would also be symptom free after five hours.
