question: Q:A researcher is conducting a study to compare fracture risk in male patients above the age of 65 who received annual DEXA screening to peers who did not receive screening. He conducts a randomized controlled trial in 900 patients, with half of participants assigned to each experimental group. The researcher ultimately finds similar rates of fractures in the two groups. He then notices that he had forgotten to include 400 patients in his analysis. Including the additional participants in his analysis would most likely affect the study's results in which of the following ways?? 
  {'A': 'Decreased significance level of results', 'B': 'Wider confidence intervals of results', 'C': 'Increased probability of committing a type II error', 'D': 'Increased probability of rejecting the null hypothesis when it is truly false', 'E': 'Increased external validity of results'},
