Several of the studies that Larry found concluded that the use of chlorhexidine mouthwash had no effect on ventilator-associated pneumonia. He noticed that the studies with smaller sample sizes found that there was no effect whereas the studies with larger sample sizes found that the number of ventilator-associated pneumonias was reduced with the use of chlorhexidine mouthwashes. What do you think might be happening? a. There was a Type I error in the smaller studies. b. There was a Type II error in the smaller studies. c. There was a Type II error in the larger studies. d. There was a Type I error in the larger studies
