Question

What would be a valid conclusion to draw from this data? A) All methods are effective in killing bacteria. B) Both soap brands out perform hand sanitizer in killing bacteria. C) Warm water is as effective as soap or sanitizer in killing bacteria. D) Hand sanitizer is more effective than either soap in killing bacteria.
