The data are provided for the results from a screening test for HIV that was performed on a group of 100,000 people. Note that the prevalence rate of HIV in this group was very low (see the below).

Find the type I error, type II error, sensitivity and specificity.(Note: I asked you to give the percentage, all of them are conditional probability based on a specific real status. Specificity+type I error=100%; sensitivity+type II error=100%)
