In trials of a medical screening test for a particular illness. 23 cases out of 324 positive results turned out to be "false-positive" results. The screening test is acceptable as long as p, the probability of a positive result being incorrect, is no larger than 10%. Calculate a p-value for the hypotheses
H0: p > 0.1 versus HA: p < 0.1
Construct a 99% upper confidence bound on p. Do you think that the screening test is acceptable?
