The Specificity of the Standard Test to Detect Disease X

The specificity of the standard test to detect disease X in the general population is 73%.  A team of researchers set forth a goal to increase specificity for detecting disease X.  They develop a new test and conduct a study to evaluate its performance on a random sample from the general population.  The results of their study are shown below. According to these results, have the researchers achieved their goal?

A) Cannot be determined because the prevalence of disease X is not provided
B) No, the researchers' new test has about 9% lower specificity than the standard test
C) No, the researchers' results lead to nearly the same specificity as the standard test
D) Yes, the researchers achieved an increase in specificity of about 12%
E) Yes, the researchers achieved an increase in specificity of about 15%
